2018-04-30i40e: fix reading LLDP configurationMariusz Stachura1-7/+84
Previous method for reading LLDP config was based on hard-coded offsets. It happened to work, because of structured architecture of the NVM memory. In the new approach, known as FLAT, we need to calculate the absolute address, instead of using relative values. Needed defines for memory location were added.

2018-04-27net: intel: Cleanup the copyright/license headersJeff Kirsher1-25/+1
After many years of having a ~30 line copyright and license header to our source files, we are finally able to reduce that to one line with the advent of the SPDX identifier. Also caught a few files missing the SPDX license identifier, so fixed them up.

2017-06-20i40e: Support firmware CEE DCB UP to TC map re-definitionGreg Bowers1-4/+7
Changes parsing of FW 4.33 AQ command Get CEE DCBX OPER CFG (0x0A07). Change is required because FW now creates the oper_prio_tc nibbles reversed from those in the CEE Priority Group sub-TLV. This change will only apply to FW 4.33 as future FW versions will use a different function to parse the CEE data.

2017-06-20i40e: Fix potential out of bound array accessSudheer Mogilappagari1-1/+3
This is a fix for the static code analysis issue where dcbcfg->numapps could be greater than size of array (i.e dcbcfg->app[I40E_DCBX_MAX_APPS]). The fix makes sure that the array is not accessed past the size of of the array (i.e. I40E_DCBX_MAX_APPS). Copyright updated to 2017.

2016-02-03i40e: Limit DCB FW version checks to X710/XL710 devicesGreg Bowers1-5/+7
X710/XL710 devices require FW version checks to properly handle DCB configurations from the FW. Newer devices do not, so limit these checks to X710/XL710.

Changes the parsing of CEE App TLVs to fill in the App selector in struct i40e_dcbx_config with the IEEE App selector so the caller doesn't have to consider whether the App came from a CEE or IEEE DCBX negotiation.

This patch adds capability to query and store the CEE DCBX DesiredCfg and RemoteCfg data from the LLDP MIB. Added new member "desired_dcbx_config" in the i40e_hw data structure to hold CEE only DesiredCfg data.

2015-10-08i40e: Add parsing for CEE DCBX TLVsNeerav Parikh1-0/+179
This patch adds parsing for CEE DCBX TLVs from the LLDP MIB. While the driver gets the DCB CEE operational configuration from Firmware using the "Get CEE DCBX Oper Config" AQ command there is a need to get the CEE DesiredCfg Tx by firmware and DCB configuration Rx from peer; for debug and other application purposes.

2015-10-07i40e: Additional checks for CEE APP priority validityNeerav Parikh1-15/+33
The firmware has added additional status information to allow software to determine if the APP priority for FCoE/iSCSI/FIP is valid or not in CEE DCBX mode. This patch adds to support those additional checks and will only add applications to the software table that have oper and sync bits set without any error.

2015-03-05i40e: Don't check operational or sync bit for App TLVNeerav Parikh1-1/+1
In CEE mode the firmware does not set the operational status bit of the application TLV status as returned from the "Get CEE DCBX Oper Cfg" AQ command. This occurs whenever a DCBX configuration is changed. This is a workaround to remove the check for the operational and sync bits of the application TLV status till a firmware fix is provided.

2014-11-18i40e: Check for LLDP AdminStatus before querying DCBXNeerav Parikh1-0/+49
This patch adds a check whether LLDP Agent's default AdminStatus is enabled or disabled on a given port. If it is disabled then it sets the DCBX status to disabled as well; and would not query firmware for any DCBX configuration data.

2014-01-17i40e: implement DCB support infastructureNeerav Parikh1-0/+469
Intel XL710 series of adapters support QoS as per the IEEE 802.1 DCB (Data Center Bridging) standard. This is supported in conjuction with: - Enhanced Transmission Selection (ETS) - IEEE 802.1Qaz - Priority Flow Control (PFC) - IEEE 802.1Qbb - DCB eXchange Protocol (DCBX) - IEEE 802.1Qaz On Intel XL710 adapters DCBX is performed by the adapter firmware. The firmware runs DCBX in willing mode and configures the port as per the DCB settings recommended by it's link partner. By default in absence of any DCBX; firmware would configure the port with a single traffic class and all of the port bandwith will be allocated to that traffic class. This patch adds functions and calls to support querying and configuring DCB using firmware APIs.
