Currently, RALUE payload is defined locally in the function that is calling the register write. With introduction of alternative register to RALUE, XMDR, it has to be possible to put multiple FIB entry operations into single register write. So in order to prepare for that, have per-work entry operation context and propagate it all the way down to the functions writing RALUE. Signed-off-by:

Currently, every FIB event is queued-up as a separate work to be processed. However, that allows to process only one FIB entry per work callback. In preparation of future XMDR register bulking of multiple FIB entries, convert to FIB event queue. Implement this by a list_head, adding new events to the end of the list in the FIB notify callback. That allows to process multiple events from the list inside the work callback. Signed-off-by:

Since the write/delete of FIB entry is going to be implemented by XMDR register for XM implementation, introduce RALUE-independent enum for op so the enum could be used in both RALUE and XMDR. Signed-off-by:

Use netdev->tstats instead of a member of qtnf_vif for storing a pointer to the per-cpu counters. This allows us to use core functionality for statistics handling. The driver sets netdev->needs_free_netdev, therefore freeing the per-cpu counters at the right point in time is a little bit tricky. Best option seems to be to use the ndo_init/ndo_uninit callbacks.

When dumping the name and NTP servers advertised by DHCP, a blank line is emitted if either of the lists is empty. This can lead to confusing issues such as the blank line getting flagged as warning. This happens because the blank line is the result of pr_cont("\n") and that may see its level corrupted by some other driver concurrently writing to the console. Fix this by making sure that the terminating newline is only emitted if at least one entry in the lists was printed before. Reported-by:Jon Hunter <jonathanh@nvidia.com> Signed-off-by:

Now that the compiler always sees the parameters passed to the DBG() macro, it gives an error message about wrong parameters. The comment says it all: /* ndev is not valid yet, so avoid passing it in. */ DBG(SMC_DEBUG_FUNC, "--> %s\n", __func__); You cannot not just pass a parameter!

Distant QRTR nodes can be accessed via an other node that acts as a bridge. When the a QRTR endpoint associated to a bridge node is released, all the linked distant nodes should also be released. This patch fixes endpoint release by: - Submitting QRTR BYE message locally on behalf of all the nodes accessible through the endpoint. - Removing all the routable node IDs from radix tree pointing to the released node endpoint.
