Hello all:

MNPDxe supported with the Recycle buffer support fro= m the below git commit,

https://github.com/tianocore/edk2/comm= it/0507449955c5c629cec196b62986afbb91203ed9#diff-fb5b97ad38efea22f5ddd745f6= e43ebdb509dc4a5aef81997ba53af5f918a47b

But many network controllers does not support the Re= cycling Tx Buffers which will cause the PXE Download failure or HTTP Boot f= ailure.

Can this feature can be controlled by a Dynamic PCD = so that the same code can work for controller which does not support Tx Buf= fer Recycling.

Thanks

Siva
