+Subject: [PATCH] udev/net-id: Fix check for address to keep interface names
+ stable (#8458)
+
+This was a bug inadvertently added by commit 73fc96c8ac0aa9.
+
+The intent of the check is to "match slot address with device by
+stripping the function" (as the comment above states it), for example
+match network device PCI address 0000:05:00.0 (including a .0 for
+function) to PCI slot address 0000:05:00, but changing that to a streq()
+call prevented the match.
+
+Change that to startswith(), which should both fix the bug and make the
+intent of the check more clear and prevent unintentional bugs from being
+introduced by future refactorings.
