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.
Do you think this means there is an issue with the patches or your test
setup?
I didn't see anything stand out as a problem to me when reading the series:

The setup is quite simple. I send broadcast traffic to the dut on which
I run l2fwd (with xdpsock) and expect the stats to increase. But after
4096 packets, the stats stop incrementing. And I see this issue only
with 64 byte packet and not with 1500 byte packets. I am suspecting
could be some race condition or some bug in our dma controller. I am
tracking this issue and post a fix for this separately.
