+Subject: [PATCH] params: avoid linux/if_ether.h in header to fix musl build
+
+On musl-based toolchains (e.g. MIPS), including <linux/if_ether.h>
+from params.h triggers a chain through net/ethernet.h ->
+netinet/if_ether.h which also defines struct ethhdr, causing a
+redefinition conflict with the direct <linux/if_ether.h> include in
+params.c.
+
+params.h only uses ETH_ALEN from that header, so define it directly
+to avoid the conflict.

-Subject: [PATCH] xdp: avoid stddef.h and size_t in BPF headers
-
-Remove <stddef.h> includes that break BPF builds on some toolchains.
-Replace size_t in xdp_sample_shared.h with unsigned long long to keep
-structs usable without stddef definitions.
