2018-11-07igc: fix error return handling from call to netif_set_real_num_tx_queuesColin Ian King1-1/+1
The call to netif_set_real_num_tx_queues is not assigning the error return to variable err even though the next line checks err for an error. Fix this by adding the missing err assignment.

2018-11-07intel-ethernet: software timestamp skbs as late as possibleJacob Keller1-2/+2
Many of the Intel Ethernet drivers call skb_tx_timestamp() earlier than necessary. Move the calls to this function to the latest point possible, just prior to notifying hardware of the new Tx packet when we bump the tail register. This affects i40e, iavf, igb, igc, and ixgbe. The e100, e1000, e1000e, fm10k, and ice drivers already call the skb_tx_timestamp() function just prior to indicating the Tx packet to hardware, so they do not need to be changed.

2018-10-17igc: Add transmit and receive fastpath and interrupt handlersSasha Neftin4-44/+1205
This patch adds support for allocating, configuring, and freeing Tx/Rx ring resources. With these changes in place the descriptor queues are in a state where they are ready to transmit or receive if provided buffers. This also adds the transmit and receive fastpath and interrupt handlers. With this code in place the network device is now able to send and receive frames over the network interface using a single queue.

2018-10-17igc: Add support for PFSasha Neftin9-1/+442
This patch adds the basic defines and structures needed by the PF for operation. With this it is possible to bring up the interface, but without being able to configure any of the filters on the interface itself. Add skeleton for a function pointers.
