Hi all,

After merging the net-next tree, today's linux-next build (arm64
defconfig) failed like this:

/tmp/next/build/net/core/sysctl_net_core.c: In function 'proc_do_rss_key':
/tmp/next/build/net/core/sysctl_net_core.c:333:23: error: implicit declaration of function 'hex_byte_pack' [-Wimplicit-function-declaration]
333 | pos = hex_byte_pack(pos, netdev_rss_key[i]);
| ^~~~~~~~~~~~~
/tmp/next/build/net/core/sysctl_net_core.c:333:21: error: assignment to 'char *' from 'int' makes pointer from integer without a cast [-Wint-conversion]
333 | pos = hex_byte_pack(pos, netdev_rss_key[i]);
| ^

Caused by commit

37b0ea8fef56c (net: expand NETDEV_RSS_KEY_LEN to 256 bytes)

I have used the tree from 20260123 instead.
