Subject: NetRxPkt: fix hash calculation of IPV6 TCP
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=2683a927ff21b54a7300ac70c3c89652f2194969;p=qemu.git

NetRxPkt: fix hash calculation of IPV6 TCP

When requested to calculate the hash for TCPV6 packet,
ignore overrides of source and destination addresses
in in extension headers.
Use these overrides when new hash type NetPktRssIpV6TcpEx
requested.
Use this type in e1000e hash calculation for IPv6 TCP, which
should take in account overrides of the addresses.
