Hi,
I met a issue of IPv6 PXE boot with 10G card 82599EB. I tried to use IPv6 to PXE boot when initrd init 10G card, I let ipv6 driver was loaded, and it needs to get ipv6 IP for PXE NFS mount. I checked the SV dhcpd6 log, it had received 10g card's request and it had sent ipv6 back. Thus, I'm not surely what the issue is. I also tried in OS level with 82599EB get ipv6 address, and it was worked fine. Should I update the driver or something?
