agch: Add VTY queue management configuration
This patch adds the following VTY commands to tune AGCH queue handling: agch-queue-management default agch-queue-management threshold THRES low LOW high HIGH Examples: agch-queue-management default Resets queue management to default parameters. agch-queue-management threshold 0 low 25 high 75 Start dropping at 25%, drop all messages above 75% queue length (relative to max queue length corresponding to T3126). Between low and high, drop with a probability interpolated linearly between 0 (low) and 1 (high). agch-queue-management threshold 50 low 0 high 0 Start dropping at 50% and continue until all IMM.ASS.REJ have been removed from the front (output) of the queue Sponsored-by: On-Waves ehf
