This patch adds support for DMA_ATTR_SKIP_CPU_SYNC and DMA_ATTR_WEAK_ORDERING. By enabling both of these for the Rx path we are able to see performance improvements on architectures that implement either one due to the fact that page mapping and unmapping only has to sync what is actually being used instead of the entire buffer. In addition by enabling the weak ordering attribute enables a performance improvement for architectures that can associate a memory ordering with a DMA buffer such as Sparc. Signed-off-by:

On some platforms, syncing a buffer for DMA is expensive. Rather than sync the whole 2K receive buffer, only synchronise the length of the frame, which will typically be the MTU, or a much smaller TCP ACK. Signed-off-by:

This patch consolidates the code for the ixgbe driver so that it is more inline with what is already in igb. The general idea is to just consolidate functions that represent logical steps in the Rx process so we can later update them more easily. Signed-off-by:

Current behaviour of "mirred redirect" action (forward) offload is a bit odd. For matched packets the action forwards them to the desired destination, but it also lets the packet duplicates to go the original way down (bridge, router, etc). That is more like "mirred mirror". Fix this by using PBS type which behaves exactly like "mirred redirect". Note that PBS does not support loopback mode.

Yuval Mintz says: ==================== qed*: Add support for PTP This patch series adds required changes for qed/qede drivers for supporting the IEEE Precision Time Protocol (PTP). Changes from previous versions: v7: Fixed Kbuild robot warnings. v6: Corrected broken loop iteration in previous version. Reduced approximation error of adjfreq. v5: Removed two divisions from the adjust-frequency loop. Resulting logic would use 8 divisions [instead of 24]. v4: Remove the loop iteration for value '0' in the qed_ptp_hw_adjfreq() implementation. v3: Use div_s64 for 64-bit divisions as do_div gives error for signed types. Incorporated review comments from Richard Cochran. - Clear timestamp resgisters as soon as timestamp is read. - Use shift operation in the place of 'divide by 16'. v2: Use do_div for 64-bit divisions. ==================== Acked-by:

Even though the port autoselection is enabled by default on AM79C970A, BNC/AUI port does not work because the link is always reported to be down. The link state reported by the chip belongs only to the TP port but the driver uses it regardless of the port used. The chip can't detect BNC/AUI link state. Disable port autoselection and use TP port by default to keep current behavior (link detection works on TP port, BNC/AUI port does not work). Implement ethtool autoneg, port and duplex configuration to allow using the BNC/AUI port. Report the TP link state only if the TP port is selected. When the port autoselection is enabled or AUI port is selected, report the link as always up. Move pcnet32_suspend() and pcnet32_clr_suspend() functions to avoid forward declarations. Signed-off-by:

The ldmvsw driver is specifically for supporting the ldom virtual networking by running in the primary ldom and using the LDC to connect the remaining ldoms to the outside world via a bridge. With TSO and GSO supported while connected the bridge, things tend to misbehave as seen in our case by delayed packets, enough to begin triggering retransmits and affecting overall throughput. By turning off advertised support for TSO and GSO we restore stable traffic flow through the bridge. Orabug: 23293104 Signed-off-by:
