This patch enables the load balancing capability of firmware and hardware to spray traffic into different cpus through separate rx msix interrupts.

This cleans up the following pieces of the Rx initialization path: - Enable the ECC memory fault interrupt in OTHER causes. - Fix an 82598 initialization of RDRXCTL when depending on RSS and VMDq to be enabled. We don't need these features enabled to safely set the MVMEN bit to allow multiple SRRCTL register mappings into the RXDCTL registers. - Fix the RSS initialization path to not stomp on DCB accidentally. When configuring the MRQC (multiple Rx queue contol) register, we want to make sure we only OR in features as necessary, instead of full assignment.

The Tx accounting when cleaning during NAPI was not completely properly. We should use the work_limit to determine when to finish cleaning, and use the same to return the cleaned status. The impact of running like this causes the NAPI clean for this Tx to get stuck in a scheduling loop, and can result in Tx not getting cleaned, ending with a Tx hang and device reset.

I found the PPP subsystem to not work properly when connecting channels with different speeds to the same bundle. Problem Description: As the "ppp_mp_explode" function fragments the sk_buff buffer evenly among the PPP channels that are connected to a certain PPP unit to make up a bundle, if we are transmitting using an upper layer protocol that requires an Ack before sending the next packet (like TCP/IP for example), we will have a bandwidth bottleneck on the slowest channel of the bundle. Let's clarify by an example. Let's consider a scenario where we have two PPP links making up a bundle: a slow link (10KB/sec) and a fast link (1000KB/sec) working at the best (full bandwidth). On the top we have a TCP/IP stack sending a 1000 Bytes sk_buff buffer down to the PPP subsystem. The "ppp_mp_explode" function will divide the buffer in two fragments of 500B each (we are neglecting all the headers, crc, flags etc?.). Before the TCP/IP stack sends out the next buffer, it will have to wait for the ACK response from the remote peer, so it will have to wait for both fragments to have been sent over the two PPP links, received by the remote peer and reconstructed. The resulting behaviour is that, rather than having a bundle working @1010KB/sec (the sum of the channels bandwidths), we'll have a bundle working @20KB/sec (the double of the slowest channels bandwidth). Problem Solution: The problem has been solved by redesigning the "ppp_mp_explode" function in such a way to make it split the sk_buff buffer according to the speeds of the underlying PPP channels (the speeds of the serial interfaces respectively attached to the PPP channels). Referring to the above example, the redesigned "ppp_mp_explode" function will now divide the 1000 Bytes buffer into two fragments whose sizes are set according to the speeds of the channels where they are going to be sent on (e.g . 10 Byets on 10KB/sec channel and 990 Bytes on 1000KB/sec channel). The reworked function grants the same performances of the original one in optimal working conditions (i.e. a bundle made up of PPP links all working at the same speed), while greatly improving performances on the bundles made up of channels working at different speeds.

The original patch was submitted last year but wasn't discussed or applied because of missing maintainer's CCs. I only fixed some formatting errors, but as I saw tulip is very badly formatted and needs further work. Original description: This patch fixes MTU problem, which occurs when using 802.1q VLANs. We should allow receiving frames of up to 1518 bytes in length, instead of 1514. Based on patch written by Ben McKeegan for 2.4.x kernels. It is archived at http://www.candelatech.com/~greear/vlan/howto.html#tulip I've adjusted a few things to make it apply on 2.6.x kernels. Tested on D-Link DFE-570TX quad-fastethernet card.
