| | | | | | | | | | | | divas_um_idi_delete_entity() Not really a problem, but nice IMHO; the Coverity static analyzer complains that we use the pointer 'e' after it has been freed, so move the freeing below the final use, even if that use is just using the value of the pointer and not actually dereferencing it.

* tg3: add support a phy at an address different than 01Hauke Mehrtens2013-10-021-19/+19
| | | | | | | | | | | | | | | When phylib was in use tg3 only searched at address 01 on the mdio bus and did not work with any other address. On the BCM4705 SoCs the switch is connected as a PHY behind the MAC driven by tg3 and it is at PHY address 30 in most cases. This is a preparation patch to allow support for such switches. phy_addr is set to TG3_PHY_MII_ADDR for all devices, which are using phylib, so this should not change any behavior.

The error occurs because, during __bond_release_one, if we release our last slave, we take on a random mac address and issue a NETDEV_CHANGEADDR notification. With an attached vlan, the vlan may see that the vlan and bond mac address were in sync, but no longer are. This triggers a call to dev_uc_add and dev_set_rx_mode, which enables IFF_PROMISC on the bond device. Then, when we complete __bond_release_one, we use the current state of the bond flags to determine if we should decrement the promiscuity of the releasing slave. But since the bond changed promiscuity state during the release operation, we incorrectly decrement the slave promisc count when it wasn't in promiscuous mode to begin with, causing the above error Fix is pretty simple, just cache the bonding flags at the start of the function and use those when determining the need to set promiscuity. This is also needed for the ALLMULTI flag CC: Jay Vosburgh <fubar@us.ibm.com> CC: Andy Gospodarek <andy@greyhouse.net> CC: Mark Wu <wudxw@linux.vnet.ibm.com> CC: "David S.

However, that function is placed in the .init section so it must be called upon driver module initialization. The problem was reported by Fenguang Wu resulting in a kernel oops because the .init section was already freed.

The stack trace reveals that the offending call is clearing carrier in mwifiex_usb suspend handler. Since commit 1499d9f "mwifiex: don't drop carrier flag over suspend" has removed the carrier flag handling over suspend/resume in SDIO and PCIe drivers, I'm removing it in USB driver too. This also fixes the bug for Surface Pro. Cc: <stable@vger.kernel.org> # 3.5+ Tested-by: Dmitry Khromov <icechrome@gmail.com> Signed-off-by: Bing Zhao <bzhao@marvell.com> Signed-off-by: John W.

In Tx AMSDU case, currently 4 bytes of garbage data is unnecessarily appended for USB packets. This sometimes leads to a firmware hang, because it may not interpret the data packet correctly. Problem is fixed by removing this redundant headroom for USB.

This is caused by an incompleted host sleep handshake between driver and firmware. Like SDIO interface, PCIe also needs to go through firmware power save events to complete the handshake for host sleep configuration. Only USB interface doesn't require power save events for hs_cfg.

On ARM architecture, this causes an alignment trap and is fixed by aligning that array with __align(sizeof(void *)). That should properly align that space according to the requirements of all architectures.
