Given we dont use anymore the struct net_device *dev argument, and this interface brings litle benefit, remove netdev_{alloc|free}_page(), to debloat include/linux/skbuff.h a bit.

2011-10-12igb: Add workaround for byte swapped VLAN on i350 local trafficAlexander Duyck3-6/+25
On i350 when traffic is looped back from a VF to the PF the value is byte swapped from the normal format.

2011-10-12igb: Drop unnecessary write of E1000_IMS from igb_msix_otherAlexander Duyck1-6/+0

2011-10-07igb: fix recent VLAN changes that would leave VLANs disabled after resetAlexander Duyck1-14/+4
This patch cleans up several issues with VLANs on igb after the recent changes that were meant to leave the VLANs enabled/disable via the netdev->features flags. Specifically the Rx VLAN settings were being dropped after reset due to the fact that they were not being restored correctly. In addition I removed the IRQ disable/enable since those were in place to protect the setting of vlgrp.

This change is meant to cleanup some of the IVAR register configuration. igb_assign_vector had become pretty large with multiple copies of the same general code for setting the IVAR. This change consolidates most of that code by adding the igb_write_ivar function which allows us just to compute the index and offset and then use that information to setup the IVAR.

There are a number of places where we have values that are stored as u16 but are being converted to int unnecessarily.

Instead of storing most of the data for the TX hot path in the stack until we are ready to write the descriptor we can save ourselves some time and effort by pushing the SKB, tx_flags, gso_size, bytecount, and protocol into the first igb_tx_buffer since that is where we will end up putting it anyway.

This change converts two tx_buffer_info index values into pointers. The advantage to this is that we reduce unnecessary computations and in the case of next_to_watch we get an added bonus of the value being able to provide additional information as a NULL value indicates it is unset versus a 0 not having any meaning for the index value.

2011-10-06igb: Consolidate creation of Tx context descriptors into a single functionAlexander Duyck1-127/+106
This patch is meant to simplify the transmit path by reducing the overhead for creating a transmit context descriptor. The current implementation is split with igb_tso and igb_tx_csum doing two separate implementations on how to setup the tx_buffer_info structure and the tx_desc. By combining them it is possible to reduce code and simplify things since now only one function will create context descriptors.

2011-10-06igb: split buffer_info into tx_buffer_info and rx_buffer_infoAlexander Duyck3-88/+92
In order to be able to improve the performance of the TX path it has been necessary to add addition info to the tx_buffer_info structure. However a side effect is that the structure has gotten larger and this in turn has also increased the size of the RX buffer info structure. In order to avoid this in the future I am splitting the single buffer_info structure into two separate ones and instead I will join them by making the buffer_info pointer in the ring a union of the two.
