2014-07-24igb: Add message when malformed packets detected by hwCarolyn Wyborny
This patch adds a check and prints the error cause register value when the hardware detects a malformed packet. This is a very unlikely scenario but has been seen occasionally, so printing the message to assist the user.

2014-07-24ixgbe: don't check minimum link when direct assigned to virtual machineJacob Keller
This patch prevents the display of the minimum link qualification check if we might be in a virtual machine. This check is incorrect and misleading in this case, since we actually don't really know what the available bandwidth is. To do so, we simply check whether each function on the bus matches our device id. If it doesn't the most likely scenario is that we're directly assigned to a virtual machine.

2014-07-24ixgbe: fix use of list_for_each in ixgbe_enumerate_functionsJacob Keller
Fix a bug in the misuse of the list_for_each macro to loop over every entry in the bus_list. Instead of attempting to loop over the list from a random entry point, go up to the bus and use the real list_head entry point. This prevents the possible read or write of unallocated or incorrectly addressed memory.

git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/net-next Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2014-07-16 This series contains updates to i40e only. Neerav adds support to get the port MAC address from firmware and adds support to the ndo_get_phys_port_id() callback to provide port specific unique ids to the netdev layer. Jakub Kicinski provides 2 fixes, first fixes i40e to never generate a software time stamp if the hardware time stamp is provided. Second fixes a race condition on queueing skb for hardware time by using a simple bit lock to avoid race conditions and leaking skbs when multiple transmit rings try to claim time stamping. Paul does some general cleanup of the driver to remove unneeded spaces, comments that are no longer valid, and break that will never get touched. Jacob Keller adds a verbose warning message when the incorrect PF attempts to control timestamping for a port to which it was not assigned. The primary intent of this message is to help debugging the reason why the SIOCSHWSTAMP ioctl has failed and to help narrow the cause of the issue. ==================== Signed-off-by: David S.

2014-07-16i40e: Add ndo_get_phys_port_id() callback supportNeerav Parikh
This patch adds a new API to get the port mac address from firmware. It also adds support to the ndo_get_phys_port_id() callback to provide port specific unique id to the netdev layer. If the adapter has a valid per-port mac address then that would be used for this purpose and is expected to be unique on a per-port basis. The information can be viewed by reading the phys_port_id attribute in sysfs for each netdev or via IF netlink interface.

2014-07-02i40e/i40evf: Do not free the dummy packet buffer synchronouslyAnjali Singhai Jain
The HW still needs to consume it and freeing it in the function that created it would mean we will be racing with the HW. The i40e_clean_tx_ring() routine will free up the buffer attached once the HW has consumed it. The clean_fdir_tx_irq function had to be fixed to handle the freeing correctly. Cases where we program more than one filter per flow (Ipv4), the code had to be changed to allocate dummy buffer multiple times since it will be freed by the clean routine. This also fixes an issue where the filter program routine was not checking if there were descriptors available for programming a filter.

2014-06-30i40evf: set flags before sending messageMitch Williams
In some circumstances, the firmware could beat us to the punch, and the reply from the PF would come back before we were able to properly modify the aq_pending and aq_required flags. This would mess up the flags and put the driver in an indeterminate state, much like Schrödinger's cat. However, unlike the cat, the driver is definitely dead. To fix this, simply set the flags before sending the request to the AQ. This way, it won't matter if the interrupt comes back too soon.
