The changes to igb were to add IPV6 support which previously was only in ixgbe, the transmit path code came from that code base, we did not see this issue in testing. Its not a simple matter of a few lines of code, I think we need to go forward not back... I'll look at the code. Jack On Fri, Ja

Dear, I experience some troubles with the igb device driver on FreeBSD 10-RC4. The kernel make a pagefault in the igb_tx_ctx_setup function when accessing to a IPv6 header. The network configuration is the following: - box acting as an IPv6 router - one interface with an IPv6 (igb0) - anothe
