Hi,
I met some issues with XL710 NIC on FreeBSD10.1.
The NIC is a dual-port 40G card with the latest NVM image. CPU is 2690 V2 with hyperthreading to 40 logical cores.
Part number as XL710-QDA2 932587.
Firmware info: f5.0 a1.5 n05.02 e80002285
Driver info: 1.4.8.
Issue1:
Within 20 queues only 16 of them are receiving packets (que0 - que15),
Que16-que19 are generating interrupt but no packet available, status/error register value are all 0.
AN# sysctl dev.ixl.2 | grep rx_packet
dev.ixl.2.pf.que0.rx_packets: 8805610
dev.ixl.2.pf.que1.rx_packets: 9348787
dev.ixl.2.pf.que2.rx_packets: 8505388
dev.ixl.2.pf.que3.rx_packets: 9928934
dev.ixl.2.pf.que4.rx_packets: 3879181
dev.ixl.2.pf.que5.rx_packets: 5579101
dev.ixl.2.pf.que6.rx_packets: 4322241
dev.ixl.2.pf.que7.rx_packets: 5788389
dev.ixl.2.pf.que8.rx_packets: 5575891
dev.ixl.2.pf.que9.rx_packets: 3743182
dev.ixl.2.pf.que10.rx_packets: 4127868
dev.ixl.2.pf.que11.rx_packets: 3878214
dev.ixl.2.pf.que12.rx_packets: 4013070
dev.ixl.2.pf.que13.rx_packets: 5146686
dev.ixl.2.pf.que14.rx_packets: 4024729
dev.ixl.2.pf.que15.rx_packets: 4736103
dev.ixl.2.pf.que16.rx_packets: 0
dev.ixl.2.pf.que17.rx_packets: 0
dev.ixl.2.pf.que18.rx_packets: 0
dev.ixl.2.pf.que19.rx_packets: 0
Issue2:
The NIC may hang under heavy stress, like putting 60Gbps traffic into it.
It may stop generating interrupt in such case.
Could you please help check the above issues?
Great thanks.
