Can anybody explain what purpose of unnamed interrupts of Mellanox
ConnectX-5 cards?
I am see 19 interrupts per card. I am mean last 16 is RX queue.
What about first 3?
Also I am see very high rate for irq287/irq306 -- is this good?

12.1-
I am try use Intel 82599ES in NETMAP mode for filtering traffic.
For SYN-flood case my application can recive (by poll(2)) about
12-13Mpps by 2 thread at X5675@3.07GHz (all other traffic don't
recived by kernel).
For ACK-flood case my application can recive (by poll(2)) only about
5.8Mpss by 2 t
I am try to use Chelsio T540-CR in netmap mode and see poor (compared
to Intel 82599ES) performance.
Same application ac receive only about 8.9Mpss, compared to 12.5Mpps
at Intel.
pmc profile show mostly time spend in:
49.76% [17802]service_nm_rxq @ /boot/kernel/if_cxgbe.ko
100.0% [17802]

I am see strange behavior of Intel ix card (82599ES 10-Gigabit
SFI/SFP+ Network Connection).
Under heavy load in NETMAP mode NIC is lost input traffic, i.e. all
packets counted as `dev.ix.1.mac_stats.rx_missed_packets`,
netstat show high traffic rate:
# netstat -nbI ix1 1

g size per balancer.
i.e. about 131072 buffers per balancer and about 512K total buffers.
How I can do this?

I am wrote NETMAP application and meet some limitation.
I am use server 16-core server.
Workers thread run mostly independend, with minimal interworking.
I am use balancer threads for distributing packet flow between worker
threads.
I am using two NETMAP pipes between balancer and workers.

What hardware (NIC) recomended for 60G+ network speed?
Chelsio limited to 54Gbit/s
Melanox don't available new drivers for ConnectX-5 and need too
expensive transmiters and connectivity.
Melanox don't available new drivers for ConnectX-4 Lx and also limited

I have autofs NFSv4 mount with /etc/nfs.map:
/NFS-nfsv4,intr,soft,sec=krb5i,gssname=host storage01:/
Currently I am see NFS hung and I am can't kill shell and can't
unmount /NFS.
Is NFSv4 mount interruptible?
Or intr support only by NFSv3?

I am trying to change MAC address and setup IPv4 address and got
error:
# ifconfig em1 ether 00:30:48:63:19:04 inet 192.168.2.1/24
ifconfig: can't set link-level netmask or broadcast
Is this posible?

Do someone work on using different RSS keys and hash fields (selecting
L2/L3/L4 or just L3 hash for example) in FreeBSD?

I see isssuse: flow routed in different queue depends of IP flags.
For example:
Total 4 queue.
UDP flow.
