#tags will be truncated to the max queued commands configuration parameter.
10.2.2 Detailed control of tagged commands
This option allows you to specify a command queue depth for each device
that supports tagged command queueing.
Example:
tag_ctrl=10/t2t3q16-t5q24/t1u2q32
will set devices queue depth as follow:
- controller #0 target #2 and target #3 -> 16 commands,
- controller #0 target #5 -> 24 commands,
- controller #1 target #1 logical unit #2 -> 32 commands,
- all other logical units (all targets, all controllers) -> 10 commands.

10.2.2 Burst max
burst=0 burst disabled
burst=255 get burst length from initial IO register settings.
burst=#x burst enabled (1<<#x burst transfers max)
#x is an integer value which is log base 2 of the burst transfers max.
By default the driver uses the maximum value supported by the chip.

led=1 enable LED support
led=0 disable LED support
Do not enable LED support if your scsi board does not use SDMS BIOS.
