net: optimize Berkeley Packet Filter (BPF) processing

Gcc is currenlty not in the ability to optimize the switch statement in
sk_run_filter() because of dense case labels. This patch replace the
OR'd labels with ordered sequenced case labels. The sk_chk_filter()
function is modified to patch/replace the original OPCODES in a
ordered but equivalent form. gcc is now in the ability to transform the
switch statement in sk_run_filter into a jump table of complexity O(1).

Until this patch gcc generates a sequence of conditional branches (O(n) of 567
byte .text segment size (arch x86_64):

7ff: 8b 06                 mov    (%rsi),%eax
801: 66 83 f8 35           cmp    $0x35,%ax
805: 0f 84 d0 02 00 00     je     adb <sk_run_filter+0x31d>
80b: 0f 87 07 01 00 00     ja     918 <sk_run_filter+0x15a>
811: 66 83 f8 15           cmp    $0x15,%ax
815: 0f 84 c5 02 00 00     je     ae0 <sk_run_filter+0x322>
81b: 77 73                 ja     890 <sk_run_filter+0xd2>
81d: 66 83 f8 04           cmp    $0x4,%ax
821: 0f 84 17 02 00 00     je     a3e <sk_run_filter+0x280>
827: 77 29                 ja     852 <sk_run_filter+0x94>
829: 66 83 f8 01           cmp    $0x1,%ax
[...]

With the modification the compiler translate the switch statement into
the following jump table fragment:

7ff: 66 83 3e 2c           cmpw   $0x2c,(%rsi)
803: 0f 87 1f 02 00 00     ja     a28 <sk_run_filter+0x26a>
809: 0f b7 06              movzwl (%rsi),%eax
80c: ff 24 c5 00 00 00 00  jmpq   *0x0(,%rax,8)
813: 44 89 e3              mov    %r12d,%ebx
816: e9 43 03 00 00        jmpq   b5e <sk_run_filter+0x3a0>
81b: 41 89 dc              mov    %ebx,%r12d
81e: e9 3b 03 00 00        jmpq   b5e <sk_run_filter+0x3a0>

Furthermore, I reordered the instructions to reduce cache line misses by
order the most common instruction to the start.

tcp: do not send reset to already closed sockets

i've found that tcp_close() can be called for an already closed
socket, but still sends reset in this case (tcp_send_active_reset())
which seems to be incorrect.  Moreover, a packet with reset is sent
with different source port as original port number has been already
cleared on socket.  Besides that incrementing stat counter for
LINUX_MIB_TCPABORTONCLOSE also does not look correct in this case.

Initially this issue was found on 2.6.18-x RHEL5 kernel, but the same
seems to be true for the current mainstream kernel (checked on
2.6.35-rc3).  Please, correct me if i missed something.

How that happens:

1) the server receives a packet for socket in TCP_CLOSE_WAIT state
   that triggers a tcp_reset():

 [<ffffffff8001eff6>] sys_close+0x85/0xc7
 [<ffffffff800622dd>] tracesys+0xd5/0xe0

So, in brief:

* a received packet for socket in TCP_CLOSE_WAIT state triggers
  tcp_reset() which clears inet_sk(sk)->num and put socket into
  TCP_CLOSE state

* an attempt to write to that socket forces inet_autobind() to get a
  new port (but the write itself fails with -EPIPE)

* tcp_close() called for socket in TCP_CLOSE state sends an active
  reset via socket with newly allocated port

This adds an additional check in tcp_close() for already closed
sockets. We do not want to send anything to closed sockets.

    u64_stats_update_begin(&stats->syncp);

    u64_stats_update_end(&stats->syncp);

While a consumer should use following template to get consistent

    u64 tbytes, tpackets;
    unsigned int start;

    do {

before submitting the skb to the qdisc and once after
it is dequeued from the qdisc just before calling

Specifically, changing TX checksum setting may cause
the warning in skb_gso_segment() to be triggered if
the checksum is calculated earlier.

This consolidates the netif_needs_gso() calls so that

e1000e: fix check for manageability on ICHx/PCH

Do not check for all the bits in E1000_FWSM_MODE_MASK when checking for
manageability on 82577/82578; only check if iAMT is enabled.  Both of the
manageability checks (for 82577/82578 and ICHx) must check the firmware
valid bit too since the other bits are only valid when the latter is set.

e1000e: separate out PHY statistics register updates

The 82577/82578 parts have half-duplex statistics in PHY registers.  These
need only be read when in half-duplex and should all be read at once rather
than one at a time to prevent excessive cycles of acquiring/releasing the
PHY semaphore.

bridge: fdb cleanup runs too often

It is common in end-node, non STP bridges to set forwarding
delay to zero; which causes the forwarding database cleanup
to run every clock tick. Change to run only as soon as needed
or at next ageing timer interval which ever is sooner.

Use round_jiffies_up macro rather than attempting round up
by changing value.
