* cxgb4: Don't use entire L2T table, use only its sliceHariprasad Shenai2015-07-081-2/+16
| | | | | | | | | The driver was retrieving the parameters for the bounds of its slice of the L2T from the firmware and then throwing those away and using the entire table. This corrects that problem. Signed-off-by: Hariprasad Shenai <hariprasad@chelsio.com> Signed-off-by: David S. Miller <davem@davemloft.net>

* cxgb4: Add API to correctly calculate tuple fieldsKumar Sanghvi2013-12-221-1/+2
| | | | | | | | | | | | | | | | | Adds API cxgb4_select_ntuple so as to enable Upper Level Drivers to correctly calculate the tuple fields. Adds constant definitions for TP_VLAN_PRI_MAP for the Compressed Filter Tuple field widths and structures and uses them. Also, the CPL Parameters field for T5 is 40 bits so we need to prototype cxgb4_select_ntuple() to calculate and return u64 values.

* cxgb4: Add T4 filter supportVipul Pandya2012-12-191-0/+3
| | | | | | | | | | | | | | | The T4 architecture is capable of filtering ingress packets at line rate using the rule in TCAM. If packet hits a rule in the TCAM then it can be either dropped or passed to the receive queues based on a rule settings. This patch adds framework for managing filters and to use T4's filter capabilities. It constructs a Firmware Filter Work Request which writes the filter at a specified index to get the work done. It hosts shadow copy of ingress filter entry to check field size limitations and save memory in the case where the filter table is large.

* chelsio: Move the Chelsio driversJeff Kirsher2011-08-101-0/+107
Moves the drivers for the Chelsio chipsets into drivers/net/ethernet/chelsio/ and the necessary Kconfig and Makefile changes. CC: Divy Le Ray <divy@chelsio.com> CC: Dimitris Michailidis <dm@chelsio.com> CC: Casey Leedom <leedom@chelsio.com> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com>
