Author: erj Date: Fri Oct 12 22:40:54 2018 New Revision: 339338 URL: https://svnweb.freebsd.org/changeset/base/339338 Log: ixl/iavf(4): Change ixlv to iavf and update it to use iflib(9) Finishes the conversion of the 40Gb Intel Ethernet drivers to iflib(9) for FreeBSD 12.0, and fixes numerous bugs in both ixl(4) and iavf(4). This commit also re-adds the VF driver to GENERIC since it now compiles and functions. The VF driver name was changed from ixlv(4) to iavf(4) because the VF driver is now intended to be used with future products, not just with Fortville/Fort Park VFs. A man page update that documents these drivers is forthcoming in a separate commit.
