Subject: [PATCH] net/af_xdp: allow probing when multiprocess is disabled
|
|
|
|
[ upstream commit 17ec9678d4647f0e90b04dc2a091e36451d16ad4 ]
|
|
|
|
If EAL multiprocess feature has been disabled via rte_mp_disable()
|
|
function, AF_XDP driver may not be able to register its IPC callback.
|
|
Previously this leads to probe failure.
|
|
This commit adds a check for this condition so that AF_XDP can still be
|
|
used even if multiprocess is disabled.
|
|
|
|
Fixes: 9876cf8316b3 ("net/af_xdp: re-enable secondary process support")
