| * | | | | | ixgbe: Move bridge mode from flag to variableDon Skidmore2015-04-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We are currently storing our BRIDGE_MODE as a bit in our adapter flags. This patch will store the actual mode instead which minimizes obfuscation and makes following patches for X550 simpler.

This call to set the Rx mode should be part of the xgbe_init function so that calls to the init function don't have to be preceded with calls to configure the Rx mode.

For example, on x86 the dma_wmb/rmb equates out to a barrer() call as the architecture is already strong ordered, and on PowerPC the call works out to a lwsync which is significantly less expensive than the sync call that was being used for wmb. I placed the new barriers between any spots that seemed to be trying to order memory/memory reads or writes, if there are any spots that involved MMIO I left the existing wmb in place as the new barriers cannot order transactions between coherent and non-coherent memories. v2: Reduced the replacments to just the spots where I could clearly identify the usage pattern.

Also fixes up an instance of this, where mcdi.c was calling efx_siena_sriov_flr. The single instance of netdev_ops should call general high level functions that can then call something adapter specific in efx_nic_type. We should only do adapter specialisation via efx_nic_type. Removal of sriov functionality from the Falcon code means that tests are needed for the presence of some callbacks. Signed-off-by: Shradha Shah <sshah@solarflare.com> Signed-off-by: David S.

Earlier vsi_idx was being passed in, which was the index in the PF's VSI array. Now we pass vsi_id as communicated by the FW to the driver. This will help with future expansion of VF and FW communication. With this in place now the VF and Virtual channel driver change to move over to VSI id use is complete and is validated.
