2019-04-01net: move skb->xmit_more hint to softnet dataFlorian Westphal
There are two reasons for this. First, the xmit_more flag conceptually doesn't fit into the skb, as xmit_more is not a property related to the skb. Its only a hint to the driver that the stack is about to transmit another packet immediately. Second, it was only done this way to not have to pass another argument to ndo_start_xmit(). We can place xmit_more in the softnet data, next to the device recursion. The recursion counter is already written to on each transmit. The "more" indicator is placed right next to it. Drivers can use the netdev_xmit_more() helper instead of skb->xmit_more to check the "more packets coming" hint. skb->xmit_more is retained (but always 0) to not cause build breakage. This change takes care of the simple s/skb->xmit_more/netdev_xmit_more()/ conversions. Remaining drivers are converted in the next patches.

Now that the NSP provides the ability to read from the SFF modules' EEPROM, we can use this interface to implement the ethtool callback. If the NSP only provides partial data, we log the event from within the driver but pass a success code to ethtool to prevent it from discarding the partial data.

The NSP now provides the ability to read from the SFF module EEPROM. Note that even if an error occurs, the NSP may still provide some of the data.

2019-04-01nfp: flower: reduce action list size by coalescing mangle actionsPieter Jansen van Vuuren
With the introduction of flow_action_for_each pedit actions are no longer grouped together, instead pedit actions are broken out per 32 byte word. This results in an inefficient use of the action list that is pushed to hardware where each 32 byte word becomes its own action. Therefore we combine groups of 32 byte word before sending the action list to hardware.

Jakub Kicinski says: ==================== nfp: flower: fix matching and pushing vlan CFI bit This patch clears up some confusion around the meaning of bit 12 for FW messages related to VLAN and flower offload. Pieter says: It fixes issues with matching, pushing and popping vlan tags. We replace the vlan CFI bit with a vlan present bit that indicates the presence of a vlan tag. We also no longer set the CFI when pushing vlan tags. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
2019-04-01nfp: flower: remove vlan CFI bit from push vlan actionPieter Jansen van Vuuren
We no longer set CFI when pushing vlan tags, therefore we remove the CFI bit from push vlan.

Replace vlan CFI bit with a vlan present bit that indicates the presence of a vlan tag. Previously the driver incorrectly assumed that an vlan id of 0 is not matchable, therefore we indicate vlan presence with a vlan present bit.
