Subject: [edk2-platforms PATCH v1 0/3] Robust Netsec Initialiation
Date: Mon, 22 Jul 2019 20:56:33 +0900 [thread overview]
Message-ID: <20190722115636.3413-1-masahisa.kojima@linaro.org> (raw)
This patch series is bugfix for the hang-up issue in Netsec driver.
Some linux distributions such as Ubuntu power down the ethernet phy
in reboot. In this case, Netsec initialization fails and
system hungs.
This patch series add the robust netsec initialization,
set ethernet phy as loopback mode to expect stable RXCLK,
and wait for media link up.
The disadvantage of this patch series is that user has to wait
several seconds until netsec driver gives up ethernet link-up
if the ethernet cable is not connected.
