Hi,
I'm trying out PF_RING ZC on our new X710 card.
When using set rss_size 1 everything seems to work fine (zcount shows correct
info and no drops)
But when using a rss_size > 1 zcount will show drops when using zc:ens4f0@0
=========================
Absolute Stats: 108'696 pkts (321'542 drops) - 93'366'591 bytes
Actual Stats: 68'199.67 pps (206'970.74 drops) - 0.48 Gbps
=========================
This only happens on @0
When using rss_size 4 zc:ens4f0@1, @2 and @3 there are no drops
=========================
Absolute Stats: 177'392 pkts (0 drops) - 138'222'078 bytes
Actual Stats: 69'277.64 pps (0.00 drops) - 0.42 Gbps
=========================
The actual stats (except for the drops) seem to be correct for @0 though.
Issue 2, probably related ?
When using zcount with rss_size x and x > 1 there will be between 0 and x
