2018-03-13cxgb4: Add HMA supportArjun Vynipadath
HMA(Host Memory Access) maps a part of host memory for T6-SO memfree cards. This commit does the following: - Query FW to check if we have HMA support. If yes, the params will return HMA size configured in FW. We will dma map memory based on this size. - Also contains changes to get HMA memory information via debugfs.

2018-03-12net: phy: set link state to down when creating the phy_deviceHeiner Kallweit
Currently the link state is initialized to "up" when the phy_device is being created. This is not consistent with the phy state being initialized to PHY_DOWN. Usually this doen't do any harm because the link state is updated once the PHY reaches state PHY_AN. However e.g. if a LAN port isn't used and the PHY remains down this inconsistency remains and calls to functions like phy_print_status() give false results. Therefore change the initialization to link being down. Signed-off-by: Heiner Kallweit <hkallweit1@gmail.com> Reviewed-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: David S.

Shannon Nelson provides three fixes to the ipsec portion of ixgbe. Make sure we are using 128-bit authentication, since it is the only size supported for hardware offload. Fixed the transmit trailer length calculation for ipsec by finding the padding value and adding it to the authentication length, then save it off so that we can put it in the transmit descriptor to tell the device where to stop the checksum calculation. Lastly, cleaned up useless and dead code. Tonghao Zhang adds a ethtool stat for receive length errors, since the driver was already collecting this counter. Arnd Bergmann fixed a warning about an used variable by "rephrasing" the code so that the compiler can see the use of the variable in question.

2018-03-12Merge branch 'mlxsw-Removing-dependency-of-mlxsw-on-GRE'David S. Miller
Ido Schimmel says: ==================== mlxsw: Removing dependency of mlxsw on GRE Petr says: mlxsw_spectrum supports offloading of a tc action mirred egress mirror to a gretap or ip6gretap netdevice, which necessitates calls to functions defined in ip_gre, ip6_gre and ip6_tunnel modules. Previously this was enabled by introducing a hard dependency of MLXSW_SPECTRUM on NET_IPGRE and IPV6_GRE. However the rest of mlxsw is careful about picking which modules are absolutely required, and therefore the better approach is to make mlxsw_spectrum tolerant of absence of one or both of the GRE flavors. One way this might be resolved is by keeping the code in mlxsw_spectrum intact, and defining defaults for functions that mlxsw_spectrum depends on. The downsides are that other modules end up littered with these do-nothing defaults; that the driver ends up carrying quite a bit of dead code; and that the driver ends up having to explicitly depend on IPV6_TUNNEL to prevent configurations where mlxsw_spectrum is compiled in and and ip6_tunnel is a module, something that it currently can treat as an implementation detail of the IPV6_GRE dependency. Alternatively, the driver should just bite the bullet and ifdef-out the code that handles configurations that are not supported. Since that's what we are doing for IPv6 dependency, let's do the same for the GRE flavors. Patch #1 introduces a wrapper function for determining the value of ipv6.sysctl.multipath_hash_policy, which defaults to 0 on non-IPv6 builds. That function is then used from spectrum_router.c, instead of the direct variable reference that was introduced there during the short window when the Spectrum driver had a hard dependency on IPv6. Patch #2 moves one function to keep together in one block all the callbacks for handling (IPv4) gretap mirroring. Patch #3 then introduces the ifdefs to hide the irrelevant code. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
2018-03-12mlxsw: spectrum: Don't depend on ip_gre and ip6_grePetr Machata
mlxsw_spectrum supports offloading of a tc action mirred egress mirror to a gretap or an ip6gretap netdevice, which necessitates calls to functions defined in ip_gre, ip6_gre and ip6_tunnel modules. Previously this was enabled by introducing a hard dependency of MLXSW_SPECTRUM on NET_IPGRE and IPV6_GRE. However the rest of mlxsw is careful about picking which modules are absolutely required, and therefore the better approach is to make mlxsw_spectrum tolerant of absence of one or both of the GRE flavors. Hence rework the NET_IPGRE and IPV6_GRE dependencies to just guard matching modularity, and hide the corresponding code in spectrum_span.c in an #if IS_ENABLED. Mark mlxsw_sp_span_entry_tunnel_parms_common as maybe unused, to muffle warnings if neither GRE flavor is selected, which seems cleaner than introducing a composite #if.
