+ in the Disable parameter takes precedence.
+
+ If the ResetMCastFilter parameter is TRUE, then the multicast address list
+ filter is disabled (irregardless of what other multicast bits are set in
+ the enable and Disable parameters). The SNP->Mode->MCastFilterCount field
+ is set to zero. The SNP->Mode->MCastFilter contents are undefined.
+
+ After enableing or disabling receive filter settings, software should
+ verify the new settings by checking the SNP->Mode->ReceeiveFilterSettings,
+ SNP->Mode->MCastFilterCount and SNP->Mode->MCastFilter fields.
+
+ Note: Some network drivers and/or devices will automatically promote
+ receive filter settings if the requested setting can not be honored.
+ For example, if a request for four multicast addresses is made and
+ the underlying hardware only supports two multicast addresses the
+ driver might set the promiscuous or promiscuous multicast receive filters
+ instead. The receiving software is responsible for discarding any extra
+ packets that get through the hardware receive filters.
+
+ If ResetMCastFilter is TRUE, then the multicast receive filter list
+ on the network interface will be reset to the default multicast receive
+ filter list. If ResetMCastFilter is FALSE, and this network interface
+ allows the multicast receive filter list to be modified, then the
+ MCastFilterCnt and MCastFilter are used to update the current multicast
+ receive filter list. The modified receive filter list settings can be
+ found in the MCastFilter field of EFI_SIMPLE_NETWORK_MODE.
+
+ This routine calls ::ReceiveFilterUpdate to update the receive
+ state in the network adapter.
+
+ @param [in] pSimpleNetwork Protocol instance pointer
+ @param [in] Enable A bit mask of receive filters to enable on the network interface.
+ @param [in] Disable A bit mask of receive filters to disable on the network interface.
+ For backward compatibility with EFI 1.1 platforms, the

+ when the ResetMCastFilter parameter is TRUE.
+ @param [in] bResetMCastFilter Set to TRUE to reset the contents of the multicast receive

+ This function is used to enable and disable the hardware and software receive
+ filters for the underlying network device.
+
+ The receive filter change is broken down into three steps:
+
+ 1. The filter mask bits that are set (ON) in the Enable parameter
+ are added to the current receive filter settings.
+
+ 2. The filter mask bits that are set (ON) in the Disable parameter
+ are subtracted from the updated receive filter settins.
+
+ 3. If the resulting filter settigns is not supported by the hardware
+ a more liberal setting is selected.
+
+ If the same bits are set in the Enable and Disable parameters, then the bits
+ in the Disable parameter takes precedence.
+
+ If the ResetMCastFilter parameter is TRUE, then the multicast address list
+ filter is disabled (irregardless of what other multicast bits are set in
+ the enable and Disable parameters). The SNP->Mode->MCastFilterCount field
+ is set to zero. The SNP->Mode->MCastFilter contents are undefined.
+
+ After enableing or disabling receive filter settings, software should
+ verify the new settings by checking the SNP->Mode->ReceeiveFilterSettings,
+ SNP->Mode->MCastFilterCount and SNP->Mode->MCastFilter fields.
+
+ Note: Some network drivers and/or devices will automatically promote
+ receive filter settings if the requested setting can not be honored.
+ For example, if a request for four multicast addresses is made and
+ the underlying hardware only supports two multicast addresses the
+ driver might set the promiscuous or promiscuous multicast receive filters
+ instead. The receiving software is responsible for discarding any extra
+ packets that get through the hardware receive filters.
+
+ If ResetMCastFilter is TRUE, then the multicast receive filter list
+ on the network interface will be reset to the default multicast receive
+ filter list. If ResetMCastFilter is FALSE, and this network interface
+ allows the multicast receive filter list to be modified, then the
+ MCastFilterCnt and MCastFilter are used to update the current multicast
+ receive filter list. The modified receive filter list settings can be
+ found in the MCastFilter field of EFI_SIMPLE_NETWORK_MODE.
+
+ This routine calls ::ReceiveFilterUpdate to update the receive
+ state in the network adapter.
+
+ @param [in] pSimpleNetwork Protocol instance pointer
+ @param [in] Enable A bit mask of receive filters to enable on the network interface.
+ @param [in] Disable A bit mask of receive filters to disable on the network interface.
+ For backward compatibility with EFI 1.1 platforms, the
+ EFI_SIMPLE_NETWORK_RECEIVE_MULTICAST bit must be set
+ when the ResetMCastFilter parameter is TRUE.
+ @param [in] bResetMCastFilter Set to TRUE to reset the contents of the multicast receive
+ filters on the network interface to their default values.
+ @param [in] MCastFilterCnt Number of multicast HW MAC address in the new MCastFilter list.
+ This value must be less than or equal to the MaxMCastFilterCnt
+ field of EFI_SIMPLE_NETWORK_MODE. This field is optional if
+ ResetMCastFilter is TRUE.
+ @param [in] pMCastFilter A pointer to a list of new multicast receive filter HW MAC

Mike,
Is there a rule that a package name should end with "Pkg"?
I thought we have but it sounds to me many packages in Silicon directory don't follow.
In this case:
1. "ASIX" folder holds the package content.
2. Pkg dsc and dec file are named as "AsixPkg".
3. PLATFORM_NAME is defined as "AsixPkg" in DSC file .
Thanks,
Ray

This is generally too big to review, but I don't see a better way tbh,
given that this was contributed as is.

Thanks Ard for the review. The cosmetic/code style changes are easy enough. For the other changes, I will need to test to make sure everything still works. I guess I will have to order an Ax88179 adapter...
Thanks,

I happened to have one of each of these dongles in my drawer, so I
managed to test them both.
Both work fine, although the 88179 one was rather slow.
In any case, the 10/100 one I tried is an Apple one (05ac:1402) which is
also supported by the 88772b driver. The only other vid/pid pair which
that old driver supports is also supported by the new one, so I think we
can drop the old one altogether. The non-b 7720 driver is also supported
by the new 10/100 driver, so we can drop the old 88772 as well, afaict.

If we can drop the old ones, I will be very happy.
I was just about to start providing some feedback on those (beyond
what you have) including bits like "drop the Hungarian notation".
Fixing those would be a fair amount of effort, and moving out of their
legacy home before that would set a bad example.

I don't object to the shout-out, but can any more information be
given? That could be useful for archeological purposes.
Through a provate git repo? If so, at what commit?
Through a .zip file? If so, what was it called?
Also, semantics - could you say "provided" rather than "contributed"?

I first thought this was a copyright line retained from using a

Yes the source is in a ZIP file that I made available here:
https://github.com/samerhaj/uefi_drivers/blob/master/UsbNetworking/Asix/zip/source/AX88179_178a_UEFI_v2.9.0_Source.zip
Will add a reference in v2

I have no clue. The code came from ASIX with these Intel copyrights. I just updated the license from
"BSD License' to "BSD-2-Clause-Patent".
I also noticed the original drivers carry the Intel copyrights, and have been so since the initial contribution:
e.g. https://github.com/tianocore/edk2/commit/8dde1f6e9574967b71dc4c6ca15cb7cfd16b38a5
I am speculating, but maybe Intel wrote the original code, and ASIX never added their copyrights?

I actually see these debug macros used in both drivers.
I can fix the #if macro above to use a #define instead of the toolchain.

Leif,
Thanks for the review. Most of these are cosmetic changes that I will take care of in v2. There are a couple that may require some experiments to figure out what works and what breaks.

Hmm... Will have to experiment with these to see what happens if I pick one or the other.
