net: ethernet: ti: am65-cpsw: fix XDP_DROP, XDP_TX and XDP_REDIRECT
The following XDP_DROP test from [1] stalls the interface after
250 packets.
~# xdb-bench drop -m native eth0
This is because new RX requests are never queued. Fix that.
The below XDP_TX test from [1] fails with a warning
[ 499.947381] XDP_WARN: xdp_update_frame_from_buff(line:277): Driver BUG: missing reserved tailroom
~# xdb-bench tx -m native eth0
Fix that by using PAGE_SIZE during xdp_init_buf().
In XDP_REDIRECT case only 1 packet was processed in rx_poll.
Fix it to process up to budget packets.
Fix all XDP error cases to call trace_xdp_exception() and drop the packet
in am65_cpsw_run_xdp().
[1] xdp-tools suite https://github.com/xdp-project/xdp-tools
Fixes: 8acacc40f733 ("net: ethernet: ti: am65-cpsw: Add minimal XDP support")
