linux-next: build failure after merge of the net-next tree

Hi all,

After merging the net-next tree, today's linux-next build (x86_64
allmodconfig) failed like this:

In file included from drivers/net/ethernet/marvell/octeontx2/af/rvu_npc_fs.c:14:

cc1: all warnings being treated as errors

Caused by commit

  c6238bc0614d ("octeontx2-af: Drop rules for NPC MCAM")

I do wonder why static structs are declared in a header file ...

I have used the net-next tree from next-20220706 for today.

I have fixed compilation errors and reposted V2 patch set.  Apologies for the trouble.
