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], [3] and [4] which are already
accepted in dpdk-next-net.

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.

[3] https://patches.dpdk.org/project/dpdk/list/?series=6407
[4] https://patches.dpdk.org/project/dpdk/list/?series=6308

v2:
 - add documentation for enable/disable callbacks
 - apply eth_err() to callback return status in
   rte_eth_dev_config_restore()
 - do not check callback vs NULL if settings match
 - reword logs in net/failsafe in accordance with review notes
 - use -E_RTE_SECONDARY in net/enic as requested in review notes
 - add acks
 - rebase

Change rte_eth_allmulticast_enable()/rte_eth_allmulticast_disable()
return value from void to int and return negative errno values
in case of error conditions.
Modify usage of these functions across the ethdev according
to new return type.

[dpdk-dev] [PATCH v2 2/7] net/failsafe: check code of allmulticast mode switch

rte_eth_allmulticast_enable()/rte_eth_allmulticast_disable() return
value was changed from void to int, so this patch modify usage
of these functions across net/failsafe according to new return type.

Try to keep all-multicast mode consistent across all active
devices in the case of failure.

[dpdk-dev] [PATCH v2 4/7] ethdev: change allmulticast callbacks to return status

[Andrew Rybchenko]

m>
 <1569329773-10185-1-git-send-email-arybchenko@solarflare.com>

From: Ivan Ilchenko <Ivan.Ilchenko@oktetlabs.ru>

Enabling/disabling of allmulticast mode is not always successful and
it should be taken into account to be able to handle it properly.

When correct return status is unclear from driver code, -EAGAIN is used.

I think it's no need to define a 'ret'.
Return -EAGAIN and return 0 is enough.

Hi Qiming,

I have already merged the patchset to the next-net, what you have mentioned
looks like a minor issue, would you be OK with as it is?

[dpdk-dev] [PATCH v2 5/7] ethdev: do nothing if all-multicast mode is applied again

[Andrew Rybchenko]

m>
 <1569329773-10185-1-git-send-email-arybchenko@solarflare.com>

Since driver callbacks return status code now, there is no necessity
to enable or disable all-multicast mode once again if it is already
successfully enabled or disabled.

Configuration restore at startup tries to ensure that configured
all-multicast mode is applied and start will return error if it fails.

Also it avoids theoretical cases when already configured all-multicast
mode is applied once again and fails. In this cases it is unclear
which value should be reported on get (configured or opposite).
