Failure of the UCAST set for base mac address fails when user configures a
duplicate mac address that matches that of another vNIC on the same port.
The bna does not handle the ucast failure and keeps this address in cache.
On disable of the vNIC, bna tries to delete the failed base mac address and the
fw asserts.
On failure of ucast address, mark ucast address set to false.

bnx2x_set_features() forces a driver reload if GRO setting is changed.
A reload makes the ethernet port unresponsive for about 5 seconds.
This is not needed in the common case LRO is enabled, as LRO
(TPA_ENABLE_FLAG) has precedence over GRO (GRO_ENABLE_FLAG)
Tested:
Verified that "ethtool -K eth0 gro {on|off}" doesn't blackout
the NIC anymore

If Link Flap Avoidance is enabled, we pull the eee settings from the hw

qlge allocates chunks from a page that it maps and unmaps that page when
the last chunk is released. When the driver is unloaded or the card is
removed, all chunks are released and the page is unmapped for the last
chunk.
However, when the last chunk of a page is not allocated and the device
is removed, that page is not unmapped. In fact, its last reference is
not put and there's also a page leak. This bug prevents a device from
being properly hotplugged.
When the DMA API debug option is enabled, the following messages show
the pending DMA allocation after we remove the driver.
This patch fixes the bug by unmapping and putting the page from the ring
if its last chunk has not been allocated.

Fix EMAC soft reset on 460EX/GT to select the right PHY clock source
before and after the soft reset.
EMAC with PHY should use the clock from PHY during soft reset.
EMAC without PHY should use the internal clock during soft reset.
PPC460EX/GT Embedded Processor Advanced User's Manual
section 28.10.1 Mode Register 0 (EMACx_MR0) states:
Note: The PHY must provide a TX Clk in order to perform a soft reset
of the EMAC. If none is present, select the internal clock
(SDR0_ETH_CFG[EMACx_PHY_CLK] = 1).
After a soft reset, select the external clock.
Without the fix, 460EX/GT-based boards with RGMII PHYs attached to
EMACs experience EMAC interrupt storm and system watchdog reset when
issuing "ifconfig eth0 down" + "ifconfig eth0 up" a few times.
The system enters endless loop of serving emac_irq() with EMACx_ISR
register stuck at value 0x10000000 (Rx parity error).
With the fix, the above issue is no longer observed.

- drop/block tagged packets when the policy is priority-tagged
- make sure VLAN stripping for received packets is set
- make sure force UP bit for the VF QP is set

Pull tile update from Chris Metcalf:
"The interesting bug fix is support for the upcoming "4.2" release of
the Tilera hypervisor, which by default launches Linux at privilege
level 2 instead of 1. The fix lets new and old hypervisors and
Linuxes interoperate more smoothly, so I've tagged it for
stable@kernel.org so that older Linuxes will be able to boot under the
newer hypervisor."

reproduce steps
1. flood ping from other machine
ping -f -s 41000 IP
2. run below script
while [ 1 ]; do ethtool -s eth0 autoneg off;
sleep 3;ethtool -s eth0 autoneg on; sleep 4; done;
You can see oops in one hour.
The reason is fec_restart clear BD but NAPI may use it.
The solution is disable NAPI and stop xmit when reset BD.
disable NAPI may sleep, so fec_restart can't be call in
atomic context.

In case of error, the function ptp_clock_register() returns ERR_PTR()
and never returns NULL. The NULL test in the return value check should
be replaced with IS_ERR().
