be2net: Allow GRE to work concurrently while a VxLAN tunnel is configured

2015-01-15T06:55:05+00:00

Other tunnels like GRE break while VxLAN offloads are enabled in Skyhawk-R. To
avoid this, we should restrict offload features on a per-packet basis in such
conditions.

net: Generalize ndo_gso_check to ndo_features_check

2014-12-26T22:20:56+00:00

GSO isn't the only offload feature with restrictions that
potentially can't be expressed with the current features mechanism.
Checksum is another although it's a general issue that could in
theory apply to anything. Even if it may be possible to
implement these restrictions in other ways, it can result in
duplicate code or inefficient per-packet behavior.

This generalizes ndo_gso_check so that drivers can remove any
features that don't make sense for a given packet, similar to
netif_skb_features(). It also converts existing driver
restrictions to the new format, completing the work that was
done to support tunnel protocols since the issues apply to
checksums as well.

By actually removing features from the set that are used to do
offloading, it solves another problem with the existing
interface. In these cases, GSO would run with the original set
of features and not do anything because it appears that
segmentation is not required.

be2net: Fix incorrect setting of tunnel offload flag in netdev features

2014-12-18T17:51:29+00:00

An earlier commit to resolve an issue with encapsulation offloads missed
setting a bit in the outer netdev features flag. This results in loss of TSO
feature on a VxLAN interface.

be2net: Export tunnel offloads only when a VxLAN tunnel is created

2014-12-11T19:37:24+00:00

The encapsulated offload flags shouldn't be unconditionally exported
to the stack. The stack expects offloading to work across all tunnel
types when those flags are set. This would break other tunnels (like
GRE) since be2net currently supports tunnel offload for VxLAN only.

Also, with VxLANs Skyhawk-R can offload only 1 UDP dport. If more
than 1 UDP port is added, we should disable offloads in that case too.

ethtool: Support for configurable RSS hash function

2014-12-09T02:07:10+00:00

This patch extends the set/get_rxfh ethtool-options for getting or
setting the RSS hash function.

It modifies drivers implementation of set/get_rxfh accordingly.

This change also delegates the responsibility of checking whether a
modification to a certain RX flow hash parameter is supported to the
driver implementation of set_rxfh.

User-kernel API is done through the new hfunc bitmask field in the
ethtool_rxfh struct. A bit set in the hfunc field is corresponding to an
index in the new string-set ETH_SS_RSS_HASH_FUNCS.

Got approval from most of the relevant driver maintainers that their
driver is using Toeplitz, and for the few that didn't answered, also
assumed it is Toeplitz.

bridge: add brport flags to dflt bridge_getlink

2014-12-03T04:01:24+00:00

To allow brport device to return current brport flags set on port.  Add
returned flags to nested IFLA_PROTINFO netlink msg built in dflt getlink.
With this change, netlink msg returned for bridge_getlink contains the port's
offloaded flag settings (the port's SELF settings).

net: Check for presence of IFLA_AF_SPEC

2014-11-26T20:29:01+00:00

ndo_bridge_setlink() is currently only called on the slave if
IFLA_AF_SPEC is set but this is a very fragile assumption and may
change in the future.
