ionic: add initial framework for XDP support Set up the basics for running Rx packets through XDP programs. Add new queue setup and teardown steps for adding/removing an XDP program, and add the call to run the XDP on a packet. The XDP frame size needs to be the MTU plus standard ethernet header, plus head room for XDP scribblings and tail room for a struct skb_shared_info. Also, at this point, we don't support XDP frags, only a single contiguous Rx buffer. This means that our page splitting is not very useful, so when XDP is in use we need to use the full Rx buffer size and not do sharing.

ionic: check cmd_regs before copying in or out Since we now have potential cases of NULL cmd_regs and info_regs during a reset recovery, and left NULL if a reset recovery has failed, we need to check that they exist before we use them. Most of the cases were covered in the original patch where we verify before doing the ioreadb() for health or cmd status. However, we need to protect a few uses of io mem that could be hit in error recovery or asynchronous threads calls as well (e.g. ethtool or devlink handlers).

net: ethtool: pass a pointer to parameters to get/set_rxfh ethtool ops The get/set_rxfh ethtool ops currently takes the rxfh (RSS) parameters as direct function arguments. This will force us to change the API (and all drivers' functions) every time some new parameters are added. This is part 1/2 of the fix, as suggested in [1]: - First simplify the code by always providing a pointer to all params (indir, key and func); the fact that some of them may be NULL seems like a weird historic thing or a premature optimization. It will simplify the drivers if all pointers are always present. - Then make the functions take a dev pointer, and a pointer to a single struct wrapping all arguments. The set_* should also take an extack.

Instead, we can set up all the new queue and descriptor allocations first, then swap them out and delete the old allocations. If the new allocations fail, we report the error, stay with the old setup and continue running. This gives us a safer path, and a smaller window of time where we're not processing traffic.

ionic: support longer tx sg lists The version 1 Tx queues can use longer SG lists than the original version 0 queues, but we need to check to see if the firmware supports the v1 Tx queues. This implements the queue type query for all queue types, and uses the information to set up for using the longer Tx SG lists. Because the Tx SG list can be longer, we need to limit the max ring length to be sure we stay inside the boundaries of a DMA allocation max size, so we lower the max Tx ring size. The driver sets its highest known version in the Q_IDENTITY command, and the FW returns the highest version that it knows, bounded by the driver's version. The negotiated version number is later used in the Q_INIT commands. Signed-off-by: Shannon Nelson <snelson@pensando.io> Signed-off-by: David S. Miller <davem@davemloft.net>

ionic: report users coalesce request The user's request for an interrupt coalescing value gets translated into a hardware value to be used with the NIC, and was getting reported back based on the hw value, which, due to hw tic resolution, could be reported as a different number than what the user originally asked for. This code now tracks both the user request and what was put into the hardware so we can report back to the user what they requested.
