igb: set skb hash type from RSS_TYPE
igb always marks the RX hash as L3 regardless of RSS_TYPE in the
advanced descriptor, which may indicate L4 (TCP/UDP) hash. This can
trigger unnecessary SW hash recalculation and breaks toeplitz selftests.
Use RSS_TYPE from pkt_info to set the correct PKT_HASH_TYPE_*
Tested by toeplitz.py with the igb RSS key get/set patches applied as
they are required for toeplitz.py (see Link below).
# ethtool -N $DEV rx-flow-hash udp4 sdfn
# ethtool -N $DEV rx-flow-hash udp6 sdfn
# python toeplitz.py | grep -E "^# Totals"
Without patch:
# Totals: pass:0 fail:12 xfail:0 xpass:0 skip:0 error:0
With patch:
# Totals: pass:12 fail:0 xfail:0 xpass:0 skip:0 error:0
