Now that the 32bit UP oddity is gone and 32bit uses always a sequence
count, there is no need for the fetch_irq() variants anymore.
Convert to the regular interface.

The current implementation of fun_xdp_tx(), used for XPD_TX, is
incorrect in that it takes an address/length pair and later releases it
with page_frag_free(). It is OK for XDP_TX but the same code is used by
ndo_xdp_xmit. In that case it loses the XDP memory type and releases the
packet incorrectly for some of the types. Assorted breakage follows.
Change fun_xdp_tx() to take xdp_frame and rely on xdp_return_frame() in
reclaim.

Stephen Rothwell reported the following failure on powerpc:
ERROR: modpost: ".local_memory_node"
[drivers/net/ethernet/fungible/funeth/funeth.ko] undefined!
AFAICS this is because local_memory_node() is a non-inline non-exported
function when CONFIG_HAVE_MEMORYLESS_NODES=y. It is also the wrong API
to get a CPU's memory node. Use cpu_to_mem() in the two spots it's used.

Add the driver's data path. Tx handles skbs, XDP, and kTLS, Rx has skbs
and XDP. Also included are Rx and Tx queue creation/tear-down and
tracing.
