ice: add support BIG TCP on IPv6
Enable sending BIG TCP packets on IPv6 in the ice driver using generic
ipv6_hopopt_jumbo_remove helper for stripping HBH header.
Tested:
netperf -t TCP_RR -H 2001:db8:0:f101::1 -- -r80000,80000 -O MIN_LATENCY,P90_LATENCY,P99_LATENCY,TRANSACTION_RATE
Tested on two different setups. In both cases, the following settings were
applied after loading the changed driver:
ip link set dev enp175s0f1np1 gso_max_size 130000
ip link set dev enp175s0f1np1 gro_max_size 130000
ip link set dev enp175s0f1np1 mtu 9000
First setup:
Before:
Minimum 90th 99th Transaction
Latency Percentile Percentile Rate
Microseconds Latency Latency Tran/s
Microseconds Microseconds
134 279 410 3961.584
After:
Minimum 90th 99th Transaction
Latency Percentile Percentile Rate
Microseconds Latency Latency Tran/s
Microseconds Microseconds
135 178 216 6093.404
The other setup:
Before:
Minimum 90th 99th Transaction
Latency Percentile Percentile Rate
Microseconds Latency Latency Tran/s
Microseconds Microseconds
218 414 478 2944.765
After:
Minimum 90th 99th Transaction
Latency Percentile Percentile Rate
Microseconds Latency Latency Tran/s
Microseconds Microseconds
