commit a927409ce820909c344b8f1323285fd01046cc4f Author: Dmitry Chagin <[email protected]> AuthorDate: 2023-03-04 09:11:38 +0000 Commit: Dmitry Chagin <[email protected]> CommitDate: 2023-03-04 09:11:38 +0000 linux(4): Rename struct l_ifreq members names to avoid conflicts with FreeBSD For now we are using mixed names to access struct ifreq members, some of Linux (ifr_name, ifr_ifindex), others of FreeBSD. To avoid conflicts switch to use FreeBSD names.
