ced7ea6cf2 qcacmn: Add changes for Napier flow control
Adds support for flow control on convergence branch.
Allocate Tx descriptors dynamically when vdev comes up.
Tx queue is paused and unpaused internally in host based on the
stop and start thresholds.
Changes are added under compilation flag QCA_LL_TX_FLOW_CONTROL_V2.

bea353e14c qcacmn: Set the Tx completion ring size to appropriate value
Size the completion ring using following 2 parameters
 - NAPI schedule latency (assuming 1 netdev, gmac, competing for CPU) = 20ms
								 (2 jiffies)
 - Worst case PPS requirement = 400K PPS
    Ring size = 20 * 400 = 8000

1018547152 qcacmn: Fix LMAC interrupt mappings
Current data-path interrupt registration/handling assumes PDEV indices to be
in same order as HW MAC IDs, which is not always true. Fixed this by adding
wlan_cfg api to set and get pdev index to mac id mapping.

45b1df25fc qcacmn: Configure DP interrupt mitigation values based on ring type
Currently interrupt mitigation values are configured for per-packet interrupts.
Change this for core DP rings (REO Destination and WBM Tx Completions) to reduce
CPU overhead of interrupt processing

82ac62ecca qcacmn: Fix double free irq of external group interrupts
The irq entry for rx_err, rx_wdm_release, and reo_status
gets assigned for more than one context and this causes
double free irq during driver unload time. Fix the same

6b0d2a800c qcacmn: Add a configure interface to get max_peers from OL_IF to DP
Currently max_peer value is hardcoded with DP wlan_cfg. This change adds
a generic interface to obtain a configuration parameter from OL_IF and
store in DP

Refactor lithium datapath configuration items. This is a placeholder
for now. The actual configuration should come from target or the
platform configuration.

590aeb60c8 qcacmn: Properly export wlan_cfg API
Currently some of the public functions in wlan_cfg.c do not have their
prototypes exposed in a header file. This causes compilation warnings
when the driver is compiled with the -Wmissing-prototypes switch.  Fix
these issues by adding the prototypes to wlan_cfg.h.

d41d6d6a49 qcacmn: Add configuration interace for Lithium Datapath
Add a generic framework (wlan_cfg) for all configuration parameters
(eg.number of tx/rx rings) used by DP. Define all the parameters
as macro constants. We will later enhance wlan_cfg framework to
read these parameters from device tree file or ini file and populate
in DP config structures.
