Commit 7fa6f34 "AER revised" erroneously inserted an error-flow

has failed.

7fa6f34081 bnx2x: AER revised

b009aac12c bnx2x: fix occasional statistics off-by-4GB error
The UPDATE_QSTAT function introduced on February 15, 2012
in commit 1355b704b9 "bnx2x: consistent statistics after
internal driver reload" incorrectly fails to handle overflow
during addition of the lower 32-bit field of a stat.

This bug is present since 3.4-rc1 and should thus be considered
a candidate for stable 3.4+ releases.

7c6cdead7c tg3: 5715 does not link up when autoneg off
Commit d13ba512cb ("tg3: Remove
SPEED_UNKNOWN checks") cleaned up the autoneg advertisement by
removing some dead code. One effect of this change was that the
advertisement register would not be updated if autoneg is turned off.

This exposed a bug on the 5715 device w.r.t linking. The 5715 defaults
to advertise only 10Mb Full duplex. But with autoneg disabled, it needs
the configured speed enabled in the advertisement register to link up.

This patch adds the work around to advertise all speeds on the 5715 when
autoneg is disabled.

are forbidden to them. Instead of checking in each op whether the device being
driven is a virtual function or a physical function, this patch creates a

the ethtool ops of the driver in case it is driving a virtual function device.

84421b99ce tg3: Update link_up flag for phylib devices
Commit f4a46d1f46 introduced a bug where
the ifconfig stats would remain 0 for phylib devices. This is due to
tp->link_up flag never becoming true causing tg3_periodic_fetch_stats()
to return.

The link_up flag was being updated in tg3_test_and_report_link_chg()
after setting up the phy. This function however, is not called for
phylib devices since the driver does not do the phy setup.

This patch moves the link_up flag update into the common
tg3_link_report() function that gets called for phylib devices as well
for non phylib devices when the link state changes.

To avoid updating link_up twice, we replace tg3_carrier_...() calls that
are followed by tg3_link_report(), with netif_carrier_...(). We can then
remove the unused tg3_carrier_on() function.

5f3347e6e7 bnx2x: Fix intermittent long KR2 link up time
When a KR2 device is connected to a KR link-partner, sometimes it requires
disabling KR2 for the link to come up. To get a KR2 link up later, in case no
base pages are seen, the KR2 is restored. The problem was that some link
partners cleared their advertised BP/NP after around two seconds, causing the
driver to disable/enable KR2 link all the time.
The fix was to wait at least 5 seconds before checking KR2 recovery.

aebb2afd54 Merge branch 'upstream' of git://git.linux-mips.org/pub/scm/ralf/upstream-linus
Pull MIPS updates from Ralf Baechle:

 o Add basic support for the Mediatek/Ralink Wireless SoC family.

 o The Qualcomm Atheros platform is extended by support for the new
   QCA955X SoC series as well as a bunch of patches that get the code
   ready for OF support.

 o Lantiq and BCM47XX platform have a few improvements and bug fixes.

 o MIPS has sent a few patches that get the kernel ready for the
   upcoming microMIPS support.

 o The rest of the series is made up of small bug fixes and cleanups
   that relate to various parts of the MIPS code.  The biggy in there is
   a whitespace cleanup.  After I was sent another set of whitespace
   cleanup patches I decided it was the time to clean the whitespace
   "issues" for once and and that touches many files below arch/mips/.

Fix up silly conflicts, mostly due to whitespace cleanups.

02e711276d bgmac: omit the fcs
Do not include the frame check sequence when adding the skb to
netif_receive_skb(). This causes problems when this interface was
bridged to a wifi ap and a big package should be forwarded from this
Ethernet driver through a bride to the wifi client.

Pull networking fixes from David Miller:

 1) ping_err() ICMP error handler looks at wrong ICMP header, from Li
    Wei.

 2) TCP socket hash function on ipv6 is too weak, from Eric Dumazet.

 3) netif_set_xps_queue() forgets to drop mutex on errors, fix from
    Alexander Duyck.

 4) sum_frag_mem_limit() can deadlock due to lack of BH disabling, fix
    from Eric Dumazet.

 5) TCP SYN data is miscalculated in tcp_send_syn_data(), because the
    amount of TCP option space was not taken into account properly in
    this code path.  Fix from yuchung Cheng.

 6) MLX4 driver allocates device queues with the wrong size, from Kleber
    Sacilotto.

 7) sock_diag can access past the end of the sock_diag_handlers[] array,
    from Mathias Krause.

 8) vlan_set_encap_proto() makes incorrect assumptions about where
    skb->data points, rework the logic so that it works regardless of
    where skb->data happens to be.  From Jesse Gross.

 9) Fix gianfar build failure with NET_POLL enabled, from Paul
    Gortmaker.

10) Fix Ipv4 ID setting and checksum calculations in GRE driver, from
   Pravin B Shelar.

11) bgmac driver does:

        int i;

        for (i = 0; ...; ...) {
                ...
                for (i = 0; ...; ...) {

    effectively corrupting the outer loop index, use a seperate
    variable for the inner loops.  From Rafał Miłecki.
