For Rx default queue interrupts, use: UMAC_IRQ_RXDMA_BDONE | UMAC_IRQ_RXDMA_PDONE For Tx default queue interrupts, use: UMAC_IRQ_TXDMA_BDONE | UMAC_IRQ_TXDMA_PDONE Signed-off-by: Petri Gynther <pgynther@google.com> Reviewed-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: David S.

These have one host port towards the CPU and N external slave ports. To customize the driver for these new ethss sub systems, multiple compatibility strings are introduced. Currently some of parameters that are different on different variants such as number of ALE ports, stats modules and number of ports are defined through constants. These are now changed to variables in gbe_priv data that get set based on the compatibility string. This is required as there are no hardware identification registers available to distinguish among the variants of NetCP 1.5 ethss. However there is identification register available to differentiate between NetCP 1.4 vs NetCP 1.5 and the same is made use of in the code to differentiate them.

So fill this value correctly in the knav dma descriptor. Also rename dma_psflags field in struct netcp_tx_pipe to switch_to_port as it contain no flag, but the switch port number for forwarding the packet. Add a flag to hold the new flag, SWITCH_TO_PORT_IN_TAGINFO which will be set for 10G. This can also used in the future for other flags for the tx_pipe.

The conflict hunks generated by GIT were very unhelpful, to say the least. It split functions in half and moved them around, when the real actual conflict only existed solely inside of one function, that being be_map_pci_bars(). So instead, to resolve this, I checked out be_main.c from the top of net-next, then I applied the be_main.c changes from 'net' since the last time I merged. And this worked beautifully. The inet_diag.c and sysctl_net_core.c conflicts were simple overlapping changes, and were easily to resolve. Signed-off-by: David S. Miller <davem@davemloft.net>

So, for example, when setting an Rx usec of 30, it will be reported as 29. Fix this reporting issue by keeping the original usec value and using that during reporting.

Using hrtimers, the idea was to trigger a timer interrupt after having queued a packet for transmit. Unfortunately, as the timer value was lowered, the timer expired before the hardware actually did the transmit and so it was racey and resulted in unnecessary interrupts. Remove the Tx coalescing support and hrtimer and replace with a Tx timer that is used as a reclaim timer in case of inactivity.

Use this value rather than hard-coding it in the driver. Signed-off-by: Tom Lendacky <thomas.lendacky@amd.com> Signed-off-by: David S. Miller <davem@davemloft.net>

If the auto-negotiation has timed out then the start of a new auto-negotiation will begin again with a new base page being received. The state machine could be in a state that is not expecting this interrupt code which results in an error during auto-negotiation. Update the code to timestamp when the auto-negotiation starts. Should another page received interrupt code occur before auto-negotiation has completed but after the auto-negotiation timeout, then reset the state machine to allow the auto-negotiation to continue.
