Merge branch 'add-af_xdp-zero-copy-support'
Meghana Malladi says:
====================
Add AF_XDP zero copy support
This series adds AF_XDP zero coppy support to icssg driver.
Tests were performed on AM64x-EVM with xdpsock application [1].
A clear improvement is seen Transmit (txonly) and receive (rxdrop)
for 64 byte packets. 1500 byte test seems to be limited by line
rate (1G link) so no improvement seen there in packet rate
Having some issue with l2fwd as the benchmarking numbers show 0
for 64 byte packets after forwading first batch packets and I am
currently looking into it.
AF_XDP performance using 64 byte packets in Kpps.

Benchmark: XDP-SKB XDP-Native XDP-Native(ZeroCopy)
rxdrop 253 473 656
txonly 350 354 855
l2fwd 178 240 0
