+Subject: Drop bundled copy of linux/if_arp.h
+MIME-Version: 1.0
+Content-Type: text/plain; charset="utf-8"
+Content-Transfer-Encoding: 8bit
+
+As far as I can see, we use this to get a list of ARPHRD_* defines (used in
+particular for Type= in .link files). If we drop our copy, and build against
+old kernel headers, the user will have a shorter list of types available. This
+seems OK, and I don't think it's worth carrying our own version of this file
+just to have newest possible entries.
+
+7c5b9952c4f6e2b72f90edbe439982528b7cf223 recently updated this file, but we'd
+have to update it every time the kernel adds new entries. But if we look at
+the failure carefully:
+
+src/basic/arphrd-from-name.gperf:65:16: error: ‘ARPHRD_MCTP’ undeclared (first use in this function); did you mean ‘ARPHRD_FCPP’?
+ 65 | MCTP, ARPHRD_MCTP
+ | ^~
+ | ARPHRD_FCPP
+
+we see that the list we were generating was from the system headers, so it was
+only as good as the system headers anyway, without the newer entries in our
+bundled copy, if there were any. So let's make things simpler by always using
+system headers.
+
+And if somebody wants to fix things so that we always have the newest list,
+then we should just generate and store the converted list, not the full header.
+
+(cherry picked from commit e7f46ee3ae1cc66a94b293957721d68dc09d7449)
