selftests: drv-net: add BIG TCP coverage to TSO test
Add IPv4 and IPv6 test cases that exercise GSO packets under BIG TCP
size limits.
1..2
ok 1 tso.big_tcp_ipv4
ok 2 tso.big_tcp_ipv6
Both of them run the existing tx-tcp-segmentation
and tx-tcp6-segmentation tests at the increased TSO maximum.
Additionally, reserve a hugepage and transmit its content using
MSG_ZEROCOPY to produce skb fragments larger than 65536.
Check that the number of retransmissions represents a small
percentage of the total packets sent. Record the number of drops
before and after the send to catch issues with large frag
handling during segmentation.
