New Revision: 280182
URL: https://svnweb.freebsd.org/changeset/base/280182
Log:
Update to the Intel ixgbe driver:
- Split the driver into independent pf and vf loadables. This is
in preparation for SRIOV support which will be following shortly.
This also allows us to keep a seperate revision control over the
two parts, making for easier sustaining.
- Make the TX/RX code a shared/seperated file, in the old code base
the ixv code would miss fixes that went into ixgbe, this model
will eliminate that problem.
- The driver loadables will now match the device names, something that
has been requested for some time.
- Rather than a modules/ixgbe there is now modules/ix and modules/ixv
- It will also be possible to make your static kernel with only one
or the other for streamlined installs, or both.
Enjoy!
