architecture (i.e P1022DS/RDK boards). I am specifically referring to the

pretty sure you don't need this as asm-generic/ptrace.h already has a

I ran my test overnight with the TX irq time-stamping and finally got
one delayed packet. Based on the time-stamp data the packets are
getting stuck in the FEC TX FIFO.
The calls to the xmit function are spaced our on about 150 us interval
for a larger TCP socket write. The BestComm tx irq is han

Not really no, it's the sp (r1). r31 might be consider

Hi Li,
A while back DaveM mentioned that it would be good to
break out the ring allocations[1] in this driver.
I was looking at it, and in the process noticed this:
$ grep 'numQueues.*=' drivers/net/ethernet/freescale/ucc_geth.c
.numQueuesTx = 1,
.numQueuesRx = 1,
$

The current implementation of lazy interrupts handling has some
issues that this tries to address.
Except on iSeries, we don't do the various workarounds we need to
do on re-enable when returning from an interrupt, which can do an
implicit re-enable, and thus we may still lose or get delayed
