When TBF was converted to a classful qdisc, the semantic of the limit
parameter was broken. On initilization an inner bfifo qdisc is created
for backwards compatibility, when changing parameters however the new
limit is ignored and the current child qdisc remains in place.
Always replace the child qdisc by the default bfifo when limit is above
zero, otherwise don't touch the inner qdisc. Current tc version enforce
a limit above zero, other users can avoid creating the inner qdisc by
using zero.

This enables PnP support for the nsc-ircc chipset.
Since we can't fetch the chipset cfg_base from the PnP layer, we just use

Keep a bitmask of multicast groups with subscribed listeners to let
netlink users check for listeners before generating multicast
messages.
Queries don't perform any locking, which may result in false
positives, it is guaranteed however that any new subscriptions are

The recent (kernel 2.6.15.1) fix for PPTP NAT helper introduced a
bug - which only appears if DEBUGP is enabled though.
The calculation of the CID offset into a PPTP request struct is
not correct, so that at least not the correct CID is displayed
if DEBUGP is enabled.
This patch corrects CID offset calculation and introduces a #define
for that.

There was a hybrid use of standard timers and sk_timers. This caused
the reference count of the sock to be incorrect when resetting the RTO
timer. The sock reference count should now be correct, enabling its
destruction, and allowing the DCCP module to be unloaded.

This patch moves all helper related data fields of 'struct nf_conn'
into a separate structure 'struct nf_conn_help'. This new structure
is only present in conntrack entries for which we actually have a
helper loaded.
Also, this patch cleans up the nf_conntrack 'features' mechanism to
resemble what the original idea was: Just glue the feature-specific
data structures at the end of 'struct nf_conn', and explicitly
re-calculate the pointer to it when needed rather than keeping
pointers around.
Saves 20 bytes per conntrack on my x86_64 box. A non-helped conntrack
is 276 bytes. We still need to save another 20 bytes in order to fit
into to target of 256bytes.

Support bigger rx ring sizes (up to 1020) in the rx fast path.
Signed-off-by: Michael Chan <mchan@broadcom.com>
Signed-off-by: David S. Miller <davem@davemloft.net>
Increase maximum receive ring size from 255 to 1020 by supporting
up to 4 linked pages of receive descriptors. To accomodate the
higher memory usage, each physical descriptor page is allocated
separately and the software ring that keeps track of the SKBs and the
DMA addresses is allocated using vmalloc.
Some of the receive-related fields in the bp structure are re-
organized a bit for better locality of reference.
The max. was reduced to 1020 from 4080 after discussion with David
Miller.
This patch contains ring init code changes only. This next patch
contains rx data path code changes.

Fix the rx code path that does not handle the full rx ring correctly.
When the rx ring is set to the max. size (i.e. 255), the consumer and
producer indices will be the same when completing an rx packet. Fix
the rx code to handle this condition properly.

Certain ethtool operations cannot be performed after tg3_close()
because the device will go to low power state. Add return -EAGAIN
