3) FOR DRIVER CONFIGURATION
-txbufcfg
- This command can be used to set max transmit buffer size of firmware. Increasing this
- buffer size is recommended for AMSDU packets. (Default is 2048)
-
- Usage:
- echo "<n>" > txbufcfg
- cat txbufcfg
-
- where <n> is <buffer size in byte>
-
- <buffer size> - This can be 2048/4096/8192.
-
- eg:
- cat txbufcfg - This will display the current buffer size.
- echo "8192" > txbufcfg - This will change the tx buffer size of 8192.
-
- For AMSDU for work for multiple packets we may need the max tx buffer size to be
- 4096/8192.
-
- Note:- This command should be issue in disconnected state.
- Otherwise, new setting will be effected in next time associate.
- The actual tx buf size will depends on AP's capability and max transmit buffer size.
-
amsduaggrctrl
This command could be used to enable/disable a feature where firmware gives feedback to driver
regarding the optimal AMSDU buffer size to use with the current rate. Firmware will use the
