2013-04-19net: vlan: rename NETIF_F_HW_VLAN_* feature flags to NETIF_F_HW_VLAN_CTAG_*Patrick McHardy5-33/+33
Rename the hardware VLAN acceleration features to include "CTAG" to indicate that they only support CTAGs. Follow up patches will introduce 802.1ad server provider tagging (STAGs) and require the distinction for hardware not supporting acclerating both.

2013-04-16atl1: Protect atl1_suspend with CONFIG_PM_SLEEPFabio Estevam1-0/+2
commit 7b7a2bbb690 (atl1: Remove unneeded PM_OPS definitions) removed the definition of atl1_suspend for the !CONFIG_PM_SLEEP case. So only call atl1_suspend() when CONFIG_PM_SLEEP is defined and fix the following build error from randconfig: drivers/net/ethernet/atheros/atlx/atl1.c: In function 'atl1_shutdown': drivers/net/ethernet/atheros/atlx/atl1.c:2888:2: error: implicit declaration of function 'atl1_suspend' [-Werror=implicit-function-declaration] Reported-by: kbuild test robot <fengguang.wu@intel.com> Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com> Signed-off-by: David S.

2013-04-16atl1: Remove unneeded PM_OPS definitionsFabio Estevam1-9/+2
SIMPLE_DEV_PM_OPS macro can handle !CONFIG_PM_SLEEP case nicely, so there is no need to define PM_OPS for both CONFIG_PM_SLEEP and !CONFIG_PM_SLEEP cases. Remove the unneeded definitions.
