Description Mike Belanger 2024-04-01 14:44:43 UTC 
Missing call to 
ifmedia_removeall(&adapter->media);
in ena_detach.

ifmedia_add allocates memory.
entry = malloc(sizeof(*entry), M_IFADDR, M_NOWAIT);
ifmedia_removeall will free the entries.

Typically we mark bugs closed once they're merged to stable branches (if applicable).  In this case, there's an MFC timeout on the commit, so we should wait until that's done.
