2020-10-09ice: Fix pointer cast warningsBixuan Cui1-2/+2
pointers should be casted to unsigned long to avoid -Wpointer-to-int-cast warnings: drivers/net/ethernet/intel/ice/ice_flow.h:197:33: warning: cast from pointer to integer of different size drivers/net/ethernet/intel/ice/ice_flow.h:198:32: warning: cast to pointer from integer of different size Signed-off-by: Bixuan Cui <[email protected]> Tested-by: Aaron Brown <[email protected]> Signed-off-by: Tony Nguyen <[email protected]> Signed-off-by: Jakub Kicinski <[email protected]>
2020-05-22ice: Enable flex-bytes supportHenry Tieman1-0/+12
Flex-bytes allows for packet matching based on an offset and value. This is supported via the ethtool user-def option. It is specified by providing an offset followed by a 2 byte match value. Offset is measured from the start of the MAC address. The following restrictions apply to flex-bytes. The specified offset must be an even number and be smaller than 0x1fe. Example usage: ethtool -N eth0 flow-type tcp4 src-ip 192.168.0.55 dst-ip 172.16.0.55 \ src-port 12 dst-port 13 user-def 0x10ffff action 32 Signed-off-by: Henry Tieman <[email protected]> Signed-off-by: Tony Nguyen <[email protected]> Tested-by: Andrew Bowers <[email protected]> Signed-off-by: Jeff Kirsher <[email protected]>
2020-05-22ice: Initialize Flow Director resourcesHenry Tieman1-1/+31
Flow Director allows for redirection based on ntuple rules. Rules are programmed using the ethtool set-ntuple interface. Supported actions are redirect to queue and drop. Setup the initial framework to process Flow Director filters. Create and allocate resources to manage and program filters to the hardware. Filters are processed via a sideband interface; a control VSI is created to manage communication and process requests through the sideband. Upon allocation of resources, update the hardware tables to accept perfect filters.

2020-05-21ice: Add support for tunnel offloadsTony Nguyen1-0/+3
Create a boost TCAM entry for each tunnel port in order to get a tunnel PTYPE. Update netdev feature flags and implement the appropriate logic to get and set values for hardware offloads.

2020-01-25ice: Implement ethtool get/set rx-flow-hashMd Fahad Iqbal Polash1-0/+1
Provide support to change or retrieve RSS hash options for a flow type. The supported flow-types are: tcp4, tcp6, udp4, udp6, sctp4, sctp6.

2020-01-25ice: Optimize table usageTony Nguyen1-0/+10
Attempt to optimize TCAM entries and reduce table resource usage by searching for profiles that can be reused. Provide resource cleanup of both hardware and software structures.

2020-01-24ice: Allocate flow profileTony Nguyen1-0/+23
Create an extraction sequence based on the packet header protocols to be programmed and allocate a flow profile for the extraction sequence.

2020-01-24ice: Enable writing hardware filtering tablesTony Nguyen1-0/+114
Enable the driver to write the filtering hardware tables to allow for changing of RSS rules. Upon loading of DDP package, a minimal configuration should be written to hardware. Introduce and initialize structures for storing configuration and make the top level calls to configure the RSS tables to initial values. A packet segment will be created but nothing is written to hardware yet.
