Subject: [dpdk-dev] [PATCH 1/1] ethdev: fix handling of close failure
Date: Fri, 22 Jan 2021 18:58:04 +0100
Message-ID: <20210122175804.772207-1-thomas@monjalon.net> (raw)

If a failure happens when closing a port,
it was unnecessarily failing again in the function eth_err(),
because of a check against HW removal cause.
Indeed there is a big chance the port is released at this point.
Given the port is in the middle (or at the end) of a close process,
checking the error cause by accessing the port is a non-sense.
The error check is replaced by a simple return in the close function.

Bugzilla ID: 624
Fixes: 8a5a0aad5d3e ("ethdev: allow close function to return an error")
