In multi-queue environment testing, the support for VLAN-tag based steering is useful. So, this patch adds the capability to add VLAN tag (VLAN ID and Priority) to the generated Tx frame. To set the VLAN ID=10 and Priority=2 for Tx only through TxQ=3: $ xdpsock -i eth0 -t -N -z -q 3 -V -J 10 -K 2 If VLAN ID (-J) and Priority (-K) is set, it default to VLAN ID = 1 VLAN Priority = 0. For example, VLAN-tagged Tx only, xdp copy mode through TxQ=1: $ xdpsock -i eth0 -t -N -c -q 1 -V Signed-off-by: Ong Boon Leong <[email protected]> Acked-by: Song Liu <[email protected]>
To set Dest MAC address (-G|--tx-dmac) only: $ xdpsock -i eth0 -t -N -z -G aa:bb:cc:dd:ee:ff To set Source MAC address (-H|--tx-smac) only: $ xdpsock -i eth0 -t -N -z -H 11:22:33:44:55:66 To set both Dest and Source MAC address: $ xdpsock -i eth0 -t -N -z -G aa:bb:cc:dd:ee:ff \ -H 11:22:33:44:55:66 The default Dest and Source MAC address remain the same as before.

Tx cycle time is in micro-seconds unit. By combining the batch size (-b M)
and Tx cycle time (-T|--tx-cycle N), xdpsock now can transmit batch-size of
packets every N-us periodically.
For example to transmit 1 packet each 1ms cycle time for total of 2000000
packets:
$ xdpsock -i eth0 -T -N -z -T 1000 -b 1 -C 2000000

When user sets tx-pkt-count and in case where there are invalid Tx frame,
the complete_tx_only_all() process polls indefinitely. So, this patch
adds a time-out mechanism into the process so that the application
can terminate automatically after it retries 3*polling interval duration.
