* mlxsw: Move PCI id table definitions into driver modulesJiri Pirko2016-10-281-0/+63
| | | | | | | | | | | | | | | | | | | | | So far, mlxsw_pci.ko is the module that registers PCI table for all drivers (spectrum and switchx2). That is problematic for example with dracut. Since mlxsw_spectrum.ko and mlxsw_switchx2.ko are loaded dynamically from within mlxsw_core.ko, dracut does not have track of them and avoids them from being included in initramfs. So make this in an ordinary way and define the PCI tables in individual driver modules, so it can be properly loaded and included in dracut initramfs image. As a side effect, this patch could remove no longer necessary driver "kind" strings which were used to link PCI ids with individual mlxsw drivers.

* mlxsw: pci: Rename header with HW definitionsJiri Pirko2016-10-281-231/+0Star
| | | | | | | | | pci.h needs to be used for inner function declarations. So move the original one to more appropriate name, pci_hw.h. Signed-off-by: Jiri Pirko <jiri@mellanox.com> Reviewed-by: Ido Schimmel <idosch@mellanox.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* mlxsw: pci: Implement reset done checkJiri Pirko2016-03-141-0/+3
| | | | | | | | | Firmware now tells us that the reset is done by passing a magic value via register. Use it to shorten the wait in case this is supported. With old firmware, we still wait until the timeout is reached. Signed-off-by: Jiri Pirko <jiri@mellanox.com> Signed-off-by: David S. Miller <davem@davemloft.net>

* mlxsw: spectrum: Add initial support for Spectrum ASICJiri Pirko2015-10-161-0/+1
| | | | | | | | | | | | | | Add support for new generation Mellanox Spectrum ASIC, 10/25/40/50 and 100Gb/s Ethernet Switch. The initial driver implements bridge forwarding offload including bridge internal VLAN support, FDB static entries, FDB learning and HW ageing including their setup.

| | | | | | | | | | | | | Benefit from the previously introduced Mellanox Switch infrastructure and add driver for SwitchX-2 ASIC. Note that this driver is very simple now. It implements bare minimum for getting device to work on slow-path. Fast-path offload functionality is going to be added soon.
