mlx5: support BIG TCP packets
mlx5 supports LSOv2.
IPv6 gro/tcp stacks insert a temporary Hop-by-Hop header
with JUMBO TLV for big packets.
We need to ignore/skip this HBH header when populating TX descriptor.
Note that ipv6_has_hopopt_jumbo() only recognizes very specific packet
layout, thus mlx5e_sq_xmit_wqe() is taking care of this layout only.
v7: adopt unsafe_memcpy() and MLX5_UNSAFE_MEMCPY_DISCLAIMER
v2: clear hopbyhop in mlx5e_tx_get_gso_ihs()
v4: fix compile error for CONFIG_MLX5_CORE_IPOIB=y
