I've been on vacation so I missed most of this thread. I'm just
catching up now...
Ok I converted everything with Rusty's suggestion to move napi_struct
out of net_device, this was mostly mechanical but some devices took
some unanticipated amount of work.
Actually you missed
Most drivers are in good shape, although some still have very
questionable netif_rx_complete() handling, in that racy area that
Rusty and myself were discussing today.
My inclination is to wrap those sequences around with an IRQ
safe spinlock to fix the race provably, and then if

I don't see any logic to your request, only added overhead for no reason.
There may be some flawed

It will come back, most definitely.
Not speaking for Auke, but I'm pretty sure this falls under the category

Hello,
This patch makes sure we don't dereference a NULL pointer in
drivers/net/usb/pegasus.c::write_bulk_callback() in the initial
struct net_device *net = pegasus-net; assignment.
The existing code checks if 'pegasus' is NULL and bails out if
it is, so we better not touch that pointer until
Hi,
I have noticed an unexpected behaviour of a userland program sending
packets with AF_PACKET through a network device driver. The problem
is that the userland program waits on sock_wait_for_wmem() for a long
time even if the transmitter is ready and all skb packets have been
transmitted and

That's a performance/parallelization regression from current NAPI :(
That's not true since current NAPI will only run on one cpu, the
one that the interrupt triggers on.
