2016-09-13net: Remove NO_IRQ from powerpc-only network driversMichael Ellerman8-16/+15
We'd like to eventually remove NO_IRQ on powerpc, so remove usages of it from powerpc-only drivers. Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> Signed-off-by: David S. Miller <davem@davemloft.net>
2016-09-12iwlegacy: use IS_ENABLED() instead of checking for built-in or moduleJavier Martinez Canillas1-2/+2
The IS_ENABLED() macro checks if a Kconfig symbol has been enabled either built-in or as a module, use that macro instead of open coding the same. Using the macro makes the code more readable by helping abstract away some of the Kconfig built-in and module enable details.

While migrating the bcm_sf2 driver to use b53_common, we left a small piece untouched where we kept our local copy of the per-port port_vlan_ctl bitmask value.

2016-09-11nvme: make NVME_RDMA depend on BLOCKLinus Torvalds1-1/+1
Commit aa71987472a9 ("nvme: fabrics drivers don't need the nvme-pci driver") removed the dependency on BLK_DEV_NVME, but the cdoe does depend on the block layer (which used to be an implicit dependency through BLK_DEV_NVME). Otherwise you get various errors from the kbuild test robot random config testing when that happens to hit a configuration with BLOCK device support disabled.

Flip the IPv6 output path to use the l3mdev tx out hook. The VRF dst is not returned on the first FIB lookup. Instead, the dst on the skb is switched at the beginning of the IPv6 output processing to send the packet to the VRF driver on xmit. Link scope addresses (linklocal and multicast) need special handling: specifically the oif the flow struct can not be changed because we want the lookup tied to the enslaved interface. ie., the source address and the returned route MUST point to the interface scope passed in.

2016-09-10net/mlx5: Split the load/unload flow into hardware and software flowsMohamad Haj Yahia1-64/+107
Gather all software context creating/destroying in one function and call it once in the first load and in the last unload. load/unload functions will now receive indication if we need to create/destroy the software contexts. In internal/pci error do the unload/load flows without releasing the software objects. In this way we perserve the sw core state and it help us restoring old driver state after PCI error/shutdown.
