network: Allow af_packet to transmit +4 bytes for VLAN packets.

2011-02-12T05:26:32+00:00

This allows user-space to send a '1500' MTU VLAN packet on a
1500 MTU ethernet frame.  The extra 4 bytes of a VLAN header is
not usually charged against the MTU when other parts of the
network stack is transmitting vlans...

net: filter: dont block softirqs in sk_run_filter()

2011-01-19T05:33:05+00:00

Packet filter (BPF) doesnt need to disable softirqs, being fully
re-entrant and lock-less.

af_packet: eliminate pgv_to_page on some arches

2010-12-08T18:43:41+00:00

Some arches don't need flush_dcache_page(), and don't implement it, so
we can eliminate pgv_to_page() calls on those arches.

filter: constify sk_run_filter()

2010-12-08T18:30:34+00:00

this.

Fix two af_packet comments.

af_packet: remove pgv.flags

2010-12-06T20:59:07+00:00

As we can check if an address is vmalloc address with is_vmalloc_addr(),
we remove pgv.flags. Then we may get more pg_vecs.
