rence to the sb_dev XPS map as just a way to skip the lookup of the lower device XPS map for now as that would result in the wrong queue being picked.

The idea here is to try and move away from using ixgbe_select_queue and to come up with a generic way to make this work for devices going forward. By encoding this information in the netdev this can become something that can be used generically as a solution for similar setups going forward.

The general idea here is to allow subdividing the queues of a device into queue groups accessible through an upper device such as a macvlan. The idea here is to enforce the idea that an upper device has to be a single queue device, ideally with IFF_NO_QUQUE set. With that being the case we can pretty much guarantee that the tc_to_txq mappings and XPS maps for the upper device are unused. As such we could reuse those in order to support subdividing the lower device and distributing those queues between the subordinate devices. In order to distinguish between a regular set of traffic classes and if a device is carrying subordinate traffic classes I changed num_tc from a u8 to a s16 value and use the negative values to represent the subordinate pool values. So starting at -1 and running to -32768 we can encode those as pool values, and the existing values of 0 to 15 can be maintained.

This is mostly to avoid unnecessary complexity with changes I have planned that will allow us to reuse the unused tc_to_txq and XPS configuration on a single queue device to allow it to make use of a subset of queues on an underlying device.

It is intrusive data structure that stores list nodes inside action structure itself, which means it is not safe to modify such list concurrently. However, action API doesn't use any linked list specific operations on this set of actions, so it can be safely refactored into plain pointer array.

In case of existing index(and bind argument is zero), init function returns without incrementing action reference counter. Caller of action init then proceeds working with action, without actually holding reference to it. This means that action could be deleted concurrently.

Further, it seems that the do_div() macro gets confused by the fact that we pass a signed variable rather than unsigned into it. This changes the code to instead use the div_s64() helper that is meant for signed division, along with changing the constant suffix to 'll' to actually make it a 64-bit argument everywhere, fixing both of the issues I pointed out. I'm not completely convinced that this makes the code correct, but I'm fairly sure that we have two problems less than before.

However, in certain infrastructures we see that packet (NACK) duplicates and delays may cause such retransmit attempts to occur at a high rate, so that the peer doesn't have a reasonable chance to acknowledge the reception before the 100-limit is hit. This may take much less than the stipulated link tolerance time, and despite that probe/probe replies otherwise go through as normal. We now extend the criteria for link reset to also being time based. I.e., we don't reset the link until the link tolerance time is passed AND we have made 100 retransmissions attempts.
