Author: jfv Date: Tue Mar 17 18:32:28 2015 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!
