net: port TP_STORE_ADDR_PORTS_SKB macro to be tcp/udp independent 2024-03-29T19:18:24+00:00 Balazs Scheidler bazsi77@gmail.com 2024-03-26T18:05:46+00:00 a0ad11fc2632903ec0fe9cd16b07d7dd2ade8341 This patch moves TP_STORE_ADDR_PORTS_SKB() to a common header and removes the TCP specific implementation details. Previously the macro assumed the skb passed as an argument is a TCP packet, the implementation now uses an argument to the L4 header and uses that to extract the source/destination ports, which happen to be named the same in "struct tcphdr" and "struct udphdr" Reviewed-by: Jason Xing <kerneljasonxing@gmail.com> Signed-off-by: Balazs Scheidler <balazs.scheidler@axoflow.com> Link: https://lore.kernel.org/r/9e306f78260dfbbdc7353ba5f864cc027a409540.1711475011.git.balazs.scheidler@axoflow.com Signed-off-by: Jakub Kicinski <kuba@kernel.org> 
This patch moves TP_STORE_ADDR_PORTS_SKB() to a common header and removes
