The r8168 driver fails to build with Linux v6.5 because the
skb_gso_segment() is not found ...
drivers/net/ethernet/realtek/r8168_n.c:29231:24: error: implicit
declaration of function ‘skb_gso_segment’; did you mean
‘skb_gso_reset’? [-Werror=implicit-function-declaration]
segs = skb_gso_segment(skb, features);
^~~~~~~~~~~~~~~
Commit d457a0e329b0 ("net: move gso declarations and functions to their
own files") moved the definition to a new file 'net/gso.h'. Fix this by
updating the conftest Makefile to check for the presence of this header
file and use the definition generated by conftest accordingly in the
r8168 driver.
