The branch main has been updated by erj: URL: https://cgit.FreeBSD.org/src/commit/?id=409b36ad911d0a12a45c1488369b458965691379 commit 409b36ad911d0a12a45c1488369b458965691379 Author: Eric Joyner <erj@FreeBSD.org> AuthorDate: 2021-02-13 00:04:54 +0000 Commit: Eric Joyner <erj@FreeBSD.org> CommitDate: 2021-11-24 19:54:08 +0000 ixl(4): Remove iavf(4) source files Since iavf(4) no longer shares code with ixl(4) as of commit f2fbd56a8d07665bc0a5e8b7e40026b50a591e2a and now has its own directory, remove these now-unused iavf(4)-only files.
