* drivers/ieee802154: add support for the at86rf230/231 transceiversalex.bluesman.smirnov@gmail.com2012-06-273-0/+972
| | | | | | | | | | | The AT86RF231 is a feature rich, low-power 2.4 GHz radio transceiver designed for industrial and consumer ZigBee/IEEE 802.15.4, 6LoWPAN, RF4CE and high data rate 2.4 GHz ISM band applications. This patch adds support for the Atmel RF230/231 radio transceivers. Signed-off-by: Alexander Smirnov <alex.bluesman.smirnov@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

| * r8169: RxConfig hack for the 8168evl.françois romieu2012-06-231-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The 8168evl (RTL_GIGA_MAC_VER_34) based Gigabyte GA-990FXA motherboards are very prone to NETDEV watchdog problems without this change. See https://bugzilla.kernel.org/show_bug.cgi?id=42899 for instance. I don't know why it *works*. It's depressingly effective though. For the record: - the problem may go along IOMMU (AMD-Vi) errors but it really looks like a red herring. - the patch sets the RX_MULTI_EN bit. If the 8168c doc is any guide, the chipset now fetches several Rx descriptors at a time. - long ago the driver ignored the RX_MULTI_EN bit. e542a2269f232d61270ceddd42b73a4348dee2bb changed the RxConfig settings. Whatever the problem it's now labeled a regression. - Realtek's own driver can identify two different 8168evl devices (CFG_METHOD_16 and CFG_METHOD_17) where the r8169 driver only sees one. It sucks.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes a memory leak that was introduced in the 3.4 kernel. The leak occurred when FCoE was enabled and traffic was passed over the FCoE rings reserved for FCoE. The memory leak was due to us not populating the compound page information on the order 1 pages needed for FCoE.

| * | | igb: Fix incorrect RAR address entries for i210/i211 device.Carolyn Wyborny2012-06-201-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | i210/i211 device has only 16 RAR address filters like 82575, instead of 32 like i350. This patch removes the entries for i210/i211 in the get_invariants function which was setting them for 32. This ensures that they will get the default value which is the correct one.

So change phy_id_mask to resolve this problem. Although the micrel datasheet says that the 4 LSB of phyid2 register contains the chip revision number and the current driver is designed to follow this rule, in reality the chip implementation doesn't follow it.

| * | | ixgbe: Fix PHC loophole allowing misconfiguration of increment registerJacob Keller2012-06-181-2/+11

This clock is based off of the SYSTIME registers along with the TIMINCA registers. The TIMINCA register determines the increment to be added to the SYSTIME registers every DMA clock tick. This register needs to be reconfigured whenever the link-speed changes. However, the value calculated stays the same when link is down and when link is up. Misconfiguration can occur if the link status changes due to a reset, which causes the TIMINCA register to be reset. This reset puts the device in an unstable state where the SYSTIME registers stop incrementing and the PTP protocol does not function. The solution is to double check the TIMINCA value and always reset the value if the register is zero. This prevents a misconfiguration bug that halts the PHC.
