[PATCH] ehea: restore multicast and rx_errors fields

[Eric Dumazet]

Commit 239c562c94d (ehea: Add 64bit statistics) added a regression,
since we no longer report multicast & rx_errors fields, taken from
port->stats structure. These fields are updated in ehea_update_stats()
every second.

Tested, in particular, the multicast stat, pinging 224.0.0.1 from
another machine.

Thanks.

Thanks !

Maybe you could submit a followup patch, to remove the port->stats
structure and only use two u64 fields, since this driver only use two
counters in its private "stats" ?

(I cant compile this driver on my dev machine)

Yes that sounds like a good idea.

I've applied Eric's patch to 'net'.
