2020-10-09ice: fix adding IP4 IP6 Flow Director rulesDan Nowlin1-1/+61
A subsequent addition of an IP4 or IP6 rule after other rules would overwrite any existing TCAM entries of related L4 protocols(ex: tcp4 or udp6). This was due to the mask including too many TCAM entries. Add new packet type masks with bits properly excluded so rules are not overwritten.

2020-08-01ice: Fix RSS profile locksVignesh Sridhar1-6/+7
Replacing flow profile locks with RSS profile locks in the function to remove all RSS rules for a given VSI. This is to align the locks used for RSS rule addition to VSI and removal during VSI teardown to avoid a race condition owing to several iterations of the above operations. In function to get RSS rules for given VSI and protocol header replacing the pointer reference of the RSS entry with a copy of hash value to ensure thread safety.

2020-05-22ice: Enable flex-bytes supportHenry Tieman1-0/+150
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 Tieman1-6/+163
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.

2020-01-24ice: Enable writing hardware filtering tablesTony Nguyen1-0/+250
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.
