2018-07-12be2net: move rss_flags field in rss_info to ensure proper alignmentIvan Vecera1-1/+1
The current position of .rss_flags field in struct rss_info causes that fields .rsstable and .rssqueue (both 128 bytes long) crosses cache-line boundaries. Moving it at the end properly align all fields. Before patch: struct rss_info { u64 rss_flags; /* 0 8 */ u8 rsstable[128]; /* 8 128 */ /* --- cacheline 2 boundary (128 bytes) was 8 bytes ago --- */ u8 rss_queue[128]; /* 136 128 */ /* --- cacheline 4 boundary (256 bytes) was 8 bytes ago --- */ u8 rss_hkey[40]; /* 264 40 */ }; After patch: struct rss_info { u8 rsstable[128]; /* 0 128 */ /* --- cacheline 2 boundary (128 bytes) --- */ u8 rss_queue[128]; /* 128 128 */ /* --- cacheline 4 boundary (256 bytes) --- */ u8 rss_hkey[40]; /* 256 40 */ u64 rss_flags; /* 296 8 */ }; Signed-off-by: Ivan Vecera <cera@cera.cz> Signed-off-by: David S.

2018-07-12mlxsw: spectrum_span: Change LAG lower selectionPetr Machata1-1/+4
When offloading mirror-to-gretap, mlxsw needs to preroute the path that the encapsulated packet will take. That path may include a LAG device above a front panel port. So far, mlxsw resolved the path to the first up front panel slave of the LAG interface, but that only reflects administrative state of the port. It neglects to consider whether the port actually has a carrier, and what the LACP state is. So instead of checking upness of the device, check carrier state and txability.

2018-07-12team: Publish team_port_get_rcu()Petr Machata1-5/+0
A follow-up patch adds a new entry point, team_port_dev_txable(). Making it an ordinary exported function would mean that any module that may need the service in one of the supported configurations also unconditionally needs to pull in the team module, whether or not the user actually intends to create team interfaces. To prevent that, team_port_dev_txable() is defined in if_team.h, and therefore all dependencies of that function also need to be publicly-visible. Therefore move team_port_get_rcu() from team.c to if_team.h.

Today macvlan ignores the notification when a lower device goes administratively down, preventing the lack of connectivity from bubbling up.

2018-07-12Merge branch '10GbE' of ↵David S. Miller30-94/+111
git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/next-queue Jeff Kirsher says: ==================== L2 Fwd Offload & 10GbE Intel Driver Updates 2018-07-09 This patch series is meant to allow support for the L2 forward offload, aka MACVLAN offload without the need for using ndo_select_queue. The existing solution currently requires that we use ndo_select_queue in the transmit path if we want to associate specific Tx queues with a given MACVLAN interface. In order to get away from this we need to repurpose the tc_to_txq array and XPS pointer for the MACVLAN interface and use those as a means of accessing the queues on the lower device. As a result we cannot offload a device that is configured as multiqueue, however it doesn't really make sense to configure a macvlan interfaced as being multiqueue anyway since it doesn't really have a qdisc of its own in the first place. The big changes in this set are: Allow lower device to update tc_to_txq and XPS map of offloaded MACVLAN Disable XPS for single queue devices Replace accel_priv with sb_dev in ndo_select_queue Add sb_dev parameter to fallback function for ndo_select_queue Consolidated ndo_select_queue functions that appeared to be duplicates ==================== Signed-off-by: David S.

I have the start of some XPS bits in here, but I would still need to allow for configuration of the XPS maps on the queues reserved for the subordinate devices. For now I am using the reference to the sb_dev XPS map as just a way to skip the lookup of the lower device XPS map for now as that would result in the wrong queue being picked.
