2019-11-15net: stmmac: xgmac: Remove uneeded computation for RFA/RFDJose Abreu1-12/+2
RFA and RFD should not be dependent on FIFO size. In fact, the more FIFO space we have, the later we can activate Flow Control. Let's use hard-coded values for RFA and RFD for all FIFO sizes with the exception of 4k, which is a special case. Signed-off-by: Jose Abreu <[email protected]> Signed-off-by: David S.

2019-11-15mlxsw: spectrum_router: Allocate discard adjacency entry when neededIdo Schimmel1-11/+32
Commit 0c3cbbf96def ("mlxsw: Add specific trap for packets routed via invalid nexthops") allocated an adjacency entry during driver initialization whose purpose is to discard packets hitting the route pointing to it. These adjacency entries are allocated from a resource called KVD linear (KVDL). There are situations in which the user can decide to set the size of this resource (via devlink-resource) to 0, in which case the driver will not be able to load. Therefore, instead of pre-allocating this adjacency entry, simply allocate it only when needed. A variable indicating the validity of the entry is added and is used to ensure it is only allocated and written once and that it is freed after all the routes were flushed.

2019-11-15iwlwifi: mvm: don't skip mgmt tid when flushing all tidsHaim Dreyfuss3-3/+4
There are various of flows which require tids flushing (disconnection, suspend, etc...). Currently, when the driver instructs the FW to flush he masks all the data tids(0-7). However, the driver doesn't set the management tid (#15) which cause the FW not to flush it. When the FW tries to remove the mgmt queue he throws an assert since it is not an empty queue. instead of just set only the data tids set everything and let the FW ignore the invalid tids.

2019-11-14octeontx2-af: Update NPC KPU packet parsing profileHao Zheng4-3792/+11236
Updated NPC KPU packet parsing profile with support for following - Fragmentation support for IPv4 IPv6 outer header - NIX instruction header support - QinQ with TPID of 0x8100 as non inner most vlan tag, as legacy network equipments still generate QinQ packets with this configuration. - To better support RSS for tunnelled packets, udp based tunnel protocols such as vxlan, vxlan-gpe, geneve and gtpu are now captured into a separate layer E. Consequently, the inner packet headers are pushed one layer down to LF, LG, and LH accordingly. - Support for rfc7510 mpls in udp. Up to 4 MPLS labels can be parsed and captured in one layer LE. - Parser support for DSA, extended DSA and eDSA tags right after ethernet header by Marvell SOHO and Falcon switches. For extended DSA and eDSA tags, a special PKIND of 62 is used, as these tags don't contain a tpid field. - Higig2 protocol header parsing support, added a NPC_LT_LA_HIGIG2_ETHER for a combined header of HIGIG2 and Ethernet. Add a NPC_LT_LA_IH_NIX_HIGIG2_ETHER for a combined header of nix_ih, HIGIG2 and Ethernet on egress side. Also added 2 upper flags in LA to indicate the presence of nix_ih and HIGIG2. Other changes include - IPv4.TTL==0 IPv6.HLIM==0 check - Per RFC 1858, mark fragment offset == 1 as error - TCP invalid flags check - Separate error codes for outer and inner IPv4 checksum errors. - Fix a parser error when KPU parses incoming IPSec ESP and AH packets - NPC vtag capture/strip hardware expect tag pointer to point to tpid/ethertype instead of tci. So move lb_ptr to point to tpid/ethertype. - Fix npc parser error when parsing udp packets that don't have any payload. - For a single MCAM entry to match on packets with one or stacked vlan tags combine NPC_LT_LB_STAG and NPC_LT_LB_QINQ to NPC_LT_LB_STAG_QINQ. - NVGRE to have a separate ltype LD_NVGRE instead of combined with LD_GRE. - Reserve top LD/LTYPEs to support custom KPU profile fields.
