Currently we set all skbs with CHECKSUM_UNNECESSARY, even
those whose protocol we don't know. This patch just
add the CHECKSUM_COMPLETE tag for non TCP/UDP packets.

ehea: Fix synchronization between HW and SW send queue

When memory is added to / removed from a partition via the Memory DLPAR
mechanism, the eHEA driver has to do a couple of things to reflect the
memory change in its own IO address translation tables. This involves
stopping and restarting the HW queues.
During this operation, it is possible that HW and SW pointer into these
queues get out of sync. This results in a situation where packets that
are attached to a send queue are not transmitted immediately, but
delayed until further X packets have been put on the queue.

This patch detects such loss of synchronization, and resets the ehea
port when needed.

of_device is just an alias for platform_device, so remove it entirely.  Also
replace to_of_device() with to_platform_device() and update comment blocks.

This patch was initially generated from the following semantic patch, and then

Since ehea_get_stats calls ehea_h_query_ehea_port, which
can sleep, we can also sleep when allocating a page in
this function. This fixes some memory allocation failure
warnings seen under low memory conditions.

Port reset operations and memory add/remove operations need to
be serialized to avoid a kernel deadlock. The deadlock is caused
by calling the napi_disable() function twice.
Therefore we have to employ the dlpar_mem_lock in the ehea_reset_port
function as well

on the receive queue are not seen and thus delayed until the next interrupt
