2011-10-10mscan: too much data copied to CAN frame due to 16 bit accessesWolfgang Grandegger
Due to the 16 bit access to mscan registers there's too much data copied to the zero initialized CAN frame when having an odd number of bytes to copy. This patch ensures that only the requested bytes are copied by using an 8 bit access for the remaining byte.

2011-10-10mlx4_en: fix endianness with blue frame supportThadeu Lima de Souza Cascardo
The doorbell register was being unconditionally swapped. In x86, that meant it was being swapped to BE and written to the descriptor and to memory, depending on the case of blue frame support or writing to doorbell register. On PPC, this meant it was being swapped to LE and then swapped back to BE while writing to the register. But in the blue frame case, it was being written as LE to the descriptor. The fix is not to swap doorbell unconditionally, write it to the register as BE and convert it to BE when writing it to the descriptor.

2011-10-07igb: fix recent VLAN changes that would leave VLANs disabled after resetAlexander Duyck
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 converts two tx_buffer_info index values into pointers.

2011-10-06igb: Consolidate creation of Tx context descriptors into a single functionAlexander Duyck
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 Duyck
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.
