[dpdk-dev] [PATCH v2] net/ixgbe: fix port close in FreeBSD OS

[Di ChenxuX]

FreeBSD OS don't support igb_uio interrupt, so it will fail
 when unregister the interrupt callback in port close.
We can fix the issue by passing -ENOENT when check the
 return value of unregister interrupt callback function.

Fixes: f2f4990eff94 ("net/ixgbe: release port upon close")
