Only support allowed channel to avoid:
the issue of Let openwifi work at arbitrary frequency: ./sdrctl dev sdr0 set reg rf 1/5 NMPQ
the wpa_supplicant scanning does scan those not allowed channel (originally reported by our driver capabilities), but hostpad already actually uses a not allowed channel (by sdrctl) while beacon still indicates an allowed channel (hostapd rejects to run on not allowed channel). So, after wpa_supplicant discovers the beacon on a not allowed channel while the beacon contains an allowed channel, it gets confused

Easier way to set arbitrary trx frequency via register rf 1 and 5:
Create helper function ad9361_tx_calibration() and openwifi_rf_rx_update_after_tuning() for frequency tuning. No matter it is from L

Example of how to add debug channel via sysfs and access it via script --> driver

Add code for new statistics and setting channel via sysfs

Add missing code in sdr.h for the improved tx queue mechanism in previous commit

Update the RX_BD_BUF_SIZE and NUM_RX_BD in sdr.h

Add dmesg printk flag in sdr.h and use it in openwifi_rx-interrupt() accordingly

Driver changes for FPGA SPI Tx LO control
- Manually issue Tx Quadrature calibration if frequency change is more than 100MHz
- Disable FPGA SPI module before calibration
- Add xpu reg 13 to disable c

Add the missing rf_reg_val in priv

Add runtime tx/rx antenna switch support to driver

Re-structure/define drv reg idx. Add (drv) RF reg

Add the missing sdrctl reg category

Add priv->actual_tx_lo preparing for further tx/rx related setting

Disable TID in sdr.c:

By default the TID is disabled in FPGA, because we currently try to TX and RX traffic for all TIDs. So, the TID related operations in sdr.c are removed.

Add all Europe 5GHz channel support into driver

Replace some constants of number of NIC by MAX_NUM_VIF

tx_interrupt if/else optimization

use FPGA fifo count registers instead of software queue_cnt

A-MPDU tx aggregation support

A-MPDU rx aggregation support

Merge pull request #104 from open-sdr/fix_large_ping_delay_igent

Fix the issue of iGent env related big ping delay:

Fix the issue of iGent env related big ping delay:
1. The issue only happens at zcu102 side, when it is tested as AP together with zedboard
2. The issue does not happen when zcu102 is client and zedb

Fix the issue of iGent env related big ping delay:
1. The issue only happens at zcu102 side, when it is tested as AP together with zedboard
2. The issue does not happen when zcu102 is client and zedboard is AP
3. The issue (most likely) does not happen in places other than iGent (like Pablo home)
4. Sometimes it does happen at my home when I test zcu102 as AP together with COTS WiFi
5. Indeed seems like the environment related. Guess some quick small packets in the environment quickly flush/round-up/mess-up the rx dma cyclic buffer, and the rx interrupt internal static variable target_buf_idx_old loses track of the background automatic rx dma cyclic buffer
6. The fix is for all board types (zcu102, zedboard, 7035, etc)
7. The driver compiling make_all.sh script generates USE_NEW_RX_INTERRUPT macro to pre_def.h to enable the new code (while keeping the old code). You can use the script as before.
8. The logic of the fix is that exhaustive search all the rx dma cyclic buffer in rx interrupt to get packet to Linux in the first place.
