Hello all: MNPDxe supported with the Recycle buffer support from the below git commit, https://github.com/tianocore/edk2/commit/0507449955c5c629cec196b62986afbb91203ed9#diff-fb5b97ad38efea22f5ddd745f6e43ebdb509dc4a5aef81997ba53af5f918a47b But many network controllers does not support the Recycling Tx Buffers which will cause the PXE Download failure or HTTP Boot failure. Can this feature can be controlled by a Dynamic PCD so that the same code can work for controller which does not support Tx Buffer Recycling. Thanks Siva
