atm: remove the coupling to token ring support

2012-05-16T00:14:35+00:00

The token ring support is going away, so decouple
the atm support from it in advance.

atm: Convert compare_ether_addr to ether_addr_equal

2012-05-10T00:49:17+00:00

Use the new bool function ether_addr_equal to add
some clarity and reduce the likelihood for misuse
of compare_ether_addr for sorting.

pppoatm: Fix excessive queue bloat

2012-04-13T17:03:45+00:00

We discovered that PPPoATM has an excessively deep transmit queue. A
queue the size of the default socket send buffer (wmem_default) is
maintained between the PPP generic core and the ATM device.

Fix it to queue a maximum of *two* packets. The one the ATM device is
currently working on, and one more for the ATM driver to process
immediately in its TX done interrupt handler. The PPP core is designed
to feed packets to the channel with minimal latency, so that really
ought to be enough to keep the ATM device busy.

While we're at it, fix the fact that we were triggering the wakeup
tasklet on *every* pppoatm_pop() call. The comment saying "this is
inefficient, but doing it right is too hard" turns out to be overly
pessimistic... I think :)

On machines like the Traverse Geos, with a slow Geode CPU and two
high-speed ADSL2+ interfaces, there were reports of extremely high CPU
usage which could partly be attributed to the extra wakeups.

(The wakeup handling could actually be made a whole lot easier if we
 stop checking sk->sk_sndbuf altogether. Given that we now only queue
 *two* packets ever, one wonders what the point is. As it is, you could
 already deadlock the thing by setting the sk_sndbuf to a value lower
 than the MTU of the device, and it'd just block for ever.)

ppp: Replace uses of with

2012-03-05T01:41:38+00:00

Since all that include/linux/if_ppp.h does is #include ,
this replaces the occurrences of #include  with
#include .

It also corrects an error in Documentation/networking/l2tp.txt, where
it referenced include/linux/if_ppp.h as the source of some definitions
that are actually now defined in include/linux/if_pppol2tp.h.
