[PATCH 15/20] headers: add net/gso.h backport for kernels < 6.5

From: Yi Cong <[email protected]>

In v6.5 GSO helpers (skb_gso_segment, etc.) were extracted from
linux/netdevice.h into a new net/gso.h header. For older kernels,
this backport simply includes the existing headers where these
functions are already defined.
