New Revision: 335338
URL: https://svnweb.freebsd.org/changeset/base/335338
Log:
ixl(4): Update to use iflib
Update the driver to use iflib in order to bring performance,
maintainability, and (hopefully) stability benefits to the driver.
The driver currently isn't completely ported; features that are missing:
- VF driver (ixlv)
- SR-IOV host support
- RDMA support
The plan is to have these re-added to the driver before the next FreeBSD release.
