net: Fix warnings caused by MAX_SKB_FRAGS change.

2011-03-30T06:34:08+00:00

After commit a715dea3c8e9ef2771c534e05ee1d36f65987e64 ("net: Always
allocate at least 16 skb frags regardless of page size"), the value
of MAX_SKB_FRAGS can now take on either an "unsigned long" or an
"int" value.

This causes warnings like:

net/packet/af_packet.c: In function ‘tpacket_fill_skb’:
net/packet/af_packet.c:948: warning: format ‘%lu’ expects type ‘long unsigned int’, but argument 2 has type ‘int’

Fix by forcing the constant to be unsigned long, otherwise we have
a situation where the type of a system wide constant is variable.

net: Always allocate at least 16 skb frags regardless of page size

2011-03-29T05:26:32+00:00

When analysing performance of the cxgb3 on a ppc64 box I noticed that
we weren't doing much GRO merging. It turns out we are limited by the
number of SKB frags:

#define MAX_SKB_FRAGS (65536/PAGE_SIZE + 2)

With a 4kB page size we have 18 frags, but with a 64kB page size we
only have 3 frags.

I ran a single stream TCP bandwidth test to compare the performance of

net: introduce rx_handler results and logic around that

2011-03-16T19:53:54+00:00

This patch allows rx_handlers to better signalize what to do next to
it's caller. That makes skb->deliver_no_wcard no longer needed.

kernel-doc for rx_handler_result is taken from Nicolas' patch.

net: change netdev->features to u32

2011-01-24T23:32:47+00:00

Quoting Ben Hutchings: we presumably won't be defining features that
can only be enabled on 64-bit architectures.

netfilter: fix compilation when conntrack is disabled but tproxy is enabled

2011-01-12T19:25:08+00:00

The IPv6 tproxy patches split IPv6 defragmentation off of conntrack, but
failed to update the #ifdef stanzas guarding the defragmentation related
fields and code in skbuff and conntrack related code in nf_defrag_ipv6.c.

This patch adds the required #ifdefs so that IPv6 tproxy can truly be used
without connection tracking.

bnx2x: Take the distribution range definition out of skb_tx_hash()

2010-12-16T21:15:53+00:00

Move the calcualation of the Tx hash for a given hash range into a separate
function and define the skb_tx_hash(), which calculates a Tx hash for a
[0; dev->real_num_tx_queues - 1] hash values range, using this
function (__skb_tx_hash()).
