cxgb4: fix SGE queue dump destination buffer context

2020-07-09T07:39:33Z

[ Upstream commit 1992ded5d111997877a9a25205976d8d03c46814 ] The data in destination buffer is expected to be be parsed in big endian. So, use the right context.

cxgb4: fix endian conversions for L4 ports in filters

2020-07-09T07:39:33Z

[ Upstream commit 63b53b0b99cd5f2d9754a21eda2ed8e706646cc9 ] The source and destination L4 ports in filter offload need to be in CPU endian. They will finally be converted to Big Endian after all operations are done and before giving them to hardware. The L4 ports for NAT are expected to be passed as a byte stream TCB. So, treat them as such. Fixes following sparse warnings in several places: cxgb4_tc_flower.c:159:33: warning: cast from restricted __be16 cxgb4_tc_flower.c:159:33: warning: incorrect type in argument 1 (different base types) cxgb4_tc_flower.c:159:33: expected unsigned short [usertype] val cxgb4_tc_flower.c:159:33: got restricted __be16 [usertype] dst Fixes: dca4faeb812f ("cxgb4: Add LE hash collision bug fix path in LLD driver") Fixes: 62488e4b53ae ("cxgb4: add basic tc flower offload support") Fixes: 557ccbf9dfa8 ("cxgb4: add tc flower support for L3/L4 rewrite") Signed-off-by: Rahul Lakkireddy Signed-off-by: David S.

cxgb4: parse TC-U32 key values and masks natively

2020-07-09T07:39:33Z

[ Upstream commit 27f78cb245abdb86735529c13b0a579f57829e71 ] TC-U32 passes all keys values and masks in __be32 format. The parser already expects this and hence pass the value and masks in __be32 natively to the parser.
