[Qemu-devel] [PATCH 5/6] net/eth: Remove the unused tcp_hdr structure

["Philippe Mathieu-Daudé" <philmd@redhat.com>]

Commit 75020a70215 introduced 2 very similar structures:
tcp_header and tcp_hdr.

We replaced the uses of struct tcp_hdr with the equivalent
struct tcp_header. Remove the unused one.

Signed-off-by: Philippe Mathieu-Daudé <philmd@redhat.com>

I prefer the TCP_FLAG_XXX name, but there is only one single use of
TCP_FLAG_ACK vs many use of the other set, so I'm keeping the set.
