2015-09-21qeth: add layer 2 RX/TX checksum offloadingThomas Richter
Checksum offloading for send and receive is already supported for layer 3 (IP layer). This patch adds support for RX and TX hardware checksum offloading for layer 2 (MAC layer). The hardware calculates the checksum for IP UDP and TCP packets. This patch moves the hardware checksum offloading setup to the set of common functions in qeth_core_main.c. Layer 2 and layer 3 now simply call the same common functions. Also note that TX checksum offloading is always enabled. The device driver relies on the TCP/IP stack to make use of this feature.

Shannon provides updates to i40e and i40evf to resolve an issue with the nvmupdate utility. First renames a variable name to reduce confusion and to differentiate it from the actual user variable. Then added the ability to save the admin queue write back descriptor if a caller supplies a buffer for it to be saved into. Added a new GetStatus command so that the NVM update tool can query the current status instead of doing fake write requests to probe for readiness. Added wait states to the NVM update state machine to signify when waiting for an update operation to finish, whether we are in the middle of a set of write operations, or we are now idle but waiting. Then added a facility to run admin queue commands through the NVM update utility in order to allow the update tools to interact with the firmware and do special commands needed for updates and configuration changes. Also added a facility to recover the result of a previously run admin queue command. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

2015-09-17net: bcmgenet: Implement RX coalescing control knobsFlorian Fainelli
Add support for the ethtool rx-frames coalescing parameter which allows defining the number of RX interrupts per frames received. The RDMA engine supports a configurable timeout with a resolution of approximately 8.192 us. We can no longer enable the BDONE/PDONE interrupts as those would fire for each packet/buffer received, which would defeat the MBDONE interrupt purpose. The MBDONE interrupt is guaranteed to correspond to a PDONE/BDONE interrupt when the threshold is set to 1. Signed-off-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: David S.

2015-09-17net: bcmgenet: Implement TX coalescing control knobsFlorian Fainelli
Configuring the ethtool tx-frames property, which translates into N packets before a TX interrupt is the simplest configuration scheme because it requires no locking neither at the softare nor hardware level, and is completely indepedent from the link speed. Since ethtool does not allow per-tx queue coalescing parameters, we apply the same setting to any transmit queue. We can no longer enable the BDONE/PDONE interrupts as those would fire for each packet/buffer received, which would defeat the MBDONE interrupt purpose. The MBDONE interrupt is guaranteed to correspond to a PDONE/BDONE interrupt when the threshold is set to 1, but offers interrupt coalescing when the value is > 1. Since the HW is configured to generate an interrupt when the ring becomes emtpy, we have to deny any timeout/timer settings coming from user-space to indicate we can only generate an interrupt very <N> packets. While we are at it, fix the DMA_INTR_THRESHOLD_MASK value which was off by one bit (0xff vs. 0x1ff). Signed-off-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: David S.
