Add a protocol argument to the VLAN packet tagging functions. In case of HW tagging, we need that protocol available in the ndo_start_xmit functions, so it is stored in a new field in the skb.

These are copying data into 16 char arrays. They all specify that the first string can't be more than 11 characters but once you add on the "-rx-" and the NUL character there isn't space for the %d.

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).
