Subject: net/ixgbe: fix port close in FreeBSD
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=a342d2772c3c6adffabd4e087065df177b8e06e6;p=dpdk.git

net/ixgbe: fix port close in FreeBSD

FreeBSD OS doesn'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")
