[dpdk-dev] [RFC PATCH 0/3] ethdev: document more retained across restart

[Andrew Rybchenko]

The patch series tries to improve documentation of what is retained
across default restart.

Should it collect acks from all PMD maintainers to be applied?

[dpdk-dev] [RFC PATCH 1/3] ethdev: advertise MTU as retained across device stop/start

[Andrew Rybchenko]

Changing MTU in running state may return -EBUSY saying that
MTU cannot be changed when the port is running. It assumes
that changes may be done in stopped and started (but some
PMDs may reject it) state and it is logical to require that
changes done in any of these states are retained.

The documentation says MAC addresses array is retained and

Also some PMDs do not allow to change the default MAC in

I'm confused. Default MAC address isn't implied by MAC addresses array?

 From API point of view it looks as different features (at least for me):
  - default MAC address is rte_eth_dev_default_mac_addr_set()
  - MAC addresses array is 
rte_eth_dev_mac_addr_add()/rte_eth_dev_mac_addr_remove()
but it is under one umbrella in NIC features (Unicast MAC filter).

May be it is my misunderstanding.

Because default MAC address is mac_addrs[0].

More doc is better :)
If it can be thought as different features, let's document it as you do.

[dpdk-dev] [RFC PATCH 3/3] ethdev: highlight that all-multicast is retained on restart

[Andrew Rybchenko]

All-multicast is a part of receive mode configuration and it is
better to mention explicitly that it is retained across restart.

Overall makes sense to add below items into retained list, only concern if is
there any PMD conflicts with these information, they should either updated with
this patch or at least notified about expectation change.

 From my point of view it is just clarification of the required behaviour.
MTU is required because of flag which may be used to advertise that
it is impossible to change in started state (otherwise the behaviour for
different PMDs will be absolutely different).
Default MAC is just cosmetics because of MAC address list is already
mentioned and the only goal is to highlight since these are different
features from the feature list point of view.
All-multicast is a part of Rx mode.

In fact I recall that net/bonding does not preserve all-multicast
(CC maintainers). If there is an agreement to fix it, I can take
a look - it should not be hard to fix.

In general I think that notification is sufficient in this case.

I don't think bonding does anything particular because the all_multicast state of the bonding PMD isn't related to the slaves.  Currently, it's up to the applications to correctly configure multicast on the slaves.

On a side note, I don't think the registered multicast addresses are preserved across PMD stop/start (unless this has been fixed recently).

In general I think that notification is sufficient in this case.

May be I'm wrong but I think all-multicast handling should be similar to 
promiscuous mode handling in bonding: for all slaves in the case of 
round-robin, balance and broadcast, primary only in the case of active 
backup, TLB and ALB and when slave is added/removed in 802.3ad case.

Yes, that's true, but I think it is separate story.

No objection, more clarification in doxygen is always good.
