Subject: [dpdk-dev] [PATCH 0/7] ethdev: change allmulticast controls to return status
Date: Mon, 9 Sep 2019 13:13:02 +0100
Message-ID: <1568031190-16510-1-git-send-email-arybchenko@solarflare.com> (raw)

It is the fourth patch series to get rid of void returning functions
in ethdev in accordance with deprecation notice [1].

It should be applied on top of [2] and [3].
Merge conflicts with [4] are trivial (release notes only).

Functions which return void are bad since they do not provide explicit
information to the caller if everything is OK or not.
It is especially painful in the case of all-multicast mode since it is
not always supported, there are real cases when it fails to apply and
it affects traffic which is received by the port.

Driver maintainrs are encouraged to review the patch which changes
driver callbacks prototype. Changes are not always trivial when I tried
to provide real status of the operation. I used -EAGAIN when I failed
to choose better error code.

The following two drivers ignore status of internal functions and
definitely could be improved:

net/bnx2x: bnx2x_set_rx_mode() can report failure, but it is used in
other places and should be updated carefully.

net/igbvf: e1000_promisc_set_vf() provides return status, but it is
unclear how handle it properly.
