+Subject: Revert "fix build for missing ETH_ALEN definition"
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+This reverts commit c5d9a723b5159a28f547b577711787295a14fd84 as it broke
+compiling against musl libc. Might be a bug in the latter, but for the
+time being try to please both by avoiding the include and instead
+defining ETH_ALEN if unset.
+
+While being at it, move netinet/ether.h include up.
+
+Fixes: 1bdb5535f561a ("libxtables: Extend MAC address printing/parsing support")
