Hi.
I'm porting Intel 82599 series VF driver ixv(4) from Intel (see below link).
https://www.intel.com/content/www/us/en/download/645984/intel-network-adapter-virtual-function-driver-for-pcie-10-gigabit-network-connections-under-freebsd.html
It's written for FreeBSD but doesn't have iflib code.
I think it is easier than porting from FreeBSD src tree.
In my patch, many codes are shared between OpenBSD ix(4) driver.
Especially ring buffer codes are almost re-used and just linked.
Only TDT/RDT register offset is different between ix(4) and ixv(4),
I changed to store the offset into the ring buffers and refer them.
Intel driver has AIM (Adaptive Interrupt Moderation) code.
I also ported it but it's disabled for now.
When I find some evidence that improves performance in the further testing,
I will enable it.
Most of ixv(4) driver codes (if_ixv.c) and hardware control code (ixgbe_vf.c)
are taken from Intel driver. I adjusted kstat codes to see VF registers.
Internal communication (called 'mailbox') between VF and PF (Primary Function)
codes are updated to the Intel driver.
I introduced a new interface that vlan(4) driver passes the vnet id to network
drivers. VF must tell PF which vnet ids are used or VF never receive VLAN
packets.
I tested my patch X540 VF and X550 VF on ESXi and Linux qemu.
It works fine for me.
I also confirmed ix(4) works on X550 as a regression test.
Is it OK?
