2020-05-28net: dsa: sja1105: offload the Credit-Based Shaper qdiscVladimir Oltean
SJA1105, being AVB/TSN switches, provide hardware assist for the Credit-Based Shaper as described in the IEEE 8021Q-2018 document. First generation has 10 shapers, freely assignable to any of the 4 external ports and 8 traffic classes, and second generation has 16 shapers. The Credit-Based Shaper tables are accessed through the dynamic reconfiguration interface, so we have to restore them manually after a switch reset. The tables are backed up by the static config only on P/Q/R/S, and we don't want to add custom code only for that family, since the procedure that is in place now works for both. Tested with the following commands: data_rate_kbps=67000 port_transmit_rate_kbps=1000000 idleslope=$data_rate_kbps sendslope=$(($idleslope - $port_transmit_rate_kbps)) locredit=$((-0x80000000)) hicredit=$((0x7fffffff)) tc qdisc add dev swp2 root handle 1: mqprio hw 0 num_tc 8 \ map 0 1 2 3 4 5 6 7 \ queues 1@0 1@1 1@2 1@3 1@4 1@5 1@6 1@7 tc qdisc replace dev swp2 parent 1:1 cbs \ idleslope $idleslope \ sendslope $sendslope \ hicredit $hicredit \ locredit $locredit \ offload 1 Signed-off-by: Vladimir Oltean <vladimir.oltean@nxp.com> Signed-off-by: David S.

2020-05-28mt76: fix wcid allocation issuesFelix Fietkau
mt76 core uses ffs() to find the next free bit. This works well for 32 bit architectures where BITS_PER_LONG is 32. ffs only checks 32 bit values, so allocation fails on 64 bit architectures. Additionally, the wcid mask array was too small in cases where the array was not a multiple of BITS_PER_LONG. Fix this by making the wcid mask array u32 instead and use DIV_ROUND_UP for the size, just in case we ever bump it to a value that's not a multiple of 32.

2020-05-27ice: Check UMEM FQ size when allocating bufsKrzysztof Kazimierczak
If a UMEM is present on a queue when an interface/queue pair is being enabled, the driver will try to prepare the Rx buffers in advance to improve performance. However, if fill queue is shorter than HW Rx ring, the driver will report failure after getting the last address from the fill queue. This still lets the driver process the packets correctly during the NAPI poll, but leads to a constant NAPI rescheduling. Not allocating the buffers in advance would result in a potential performance decrease. Commit d57d76428ae9 ("xsk: Add API to check for available entries in FQ") provides an API that lets drivers check the number of addresses that the fill queue holds. Notify the user if fill queue is not long enough to prepare all buffers before packet processing starts, and allocate the buffers during the NAPI poll. If the fill queue size is sufficient, prepare Rx buffers in advance.

2020-05-27net/mlx5: DR, Split RX and TX lock for parallel insertionAlex Vesker
Change the locking flow to support RX and TX locks, splitting the single lock to two will allow inserting rules in parallel for RX and TX parts of the FDB. Locking the dr_domain will be done by locking the RX domain and the TX domain locks, this is mostly used for control operations on the dr_domain. When inserting rules for RX or TX the single nic_doamin RX or TX lock will be used. Splitting the lock is safe since RX and TX domains are logically separated from each other, shared objects such the send-ring and memory pool are protected by locks.

Bonded slave representors' vports must share a unique metadata for match. On enslaving event of slave representor to lag device, allocate new unique "bond_metadata" for match if this is the first slave. The subsequent enslaved representors will share the same unique "bond_metadata". On unslaving event of slave representor, reset the slave representor's vport to use its own default metadata. Replace ingress acl and rx rules of the slave representors' vports using new vport->bond_metadata.
