2012-07-10enic: remove unnecessary setting of skb->devJon Mason1-2/+0
skb->dev is being unnecessarily set after calling eth_type_trans. eth_type_trans already sets skb->dev to the proper value, thus making this unnecessary.

2012-02-20enic: Add support for fw init command on sriov vf'sRoopa Prabhu2-2/+2
This patch fixes enic_probe to do a fw init devcmd for sriov vfs.

2012-02-13enic: remove assignment of random mac on enic vfRoopa Prabhu2-6/+1
This patch removes random mac assignment on vf's. The vf's will start with a zero mac and with upcoming support in fw/driver, a vf mac can be set via the pf. vf's also support ndo_set_mac_address. This decision was made based on the fact that a random mac on a vf is not really needed. And this will reduce some of the problems with the vf's getting a new mac on every driver load/unload (one of them being udev renaming the device on ever load/unload and reboot).

2011-09-27enic: Add support for port profile association on a enic SRIOV VFRoopa Prabhu4-96/+232
This patch touchs most of the enic port profile handling code. Tried to break it into sub patches without success. The patch mainly does the following: - Port profile operations for a SRIOV VF are modified to work only via its PF - Changes the port profile static struct in struct enic to a pointer. This is because a SRIOV PF has to now hold the port profile information for all its VF's - Moved address registration for VF's during port profile ASSOCIATE time - Most changes in port profile handling code are changes related to indexing into the port profile struct array of a PF for the VF port profile information Signed-off-by: Roopa Prabhu <roprabhu@cisco.com> Signed-off-by: Sujith Sankar <ssujith@cisco.com> Signed-off-by: Christian Benvenuti <benve@cisco.com> Signed-off-by: David Wang <dwang2@cisco.com> Signed-off-by: David S.
