dropbear parameters

[EnF70]

Any chance we can specify parameters when starting dropbear?

I would like to be able to use this parameter:
-W <receive_window_buffer> (default 24576, larger may be faster, max 1MB)

I know it improves SSH tunnel performance for video streaming.
With the default value (24576) the SSH session becomes a little bit unresponsive.
I tested on a different Linux box with "-W 262144" and it seems better.

Any chance we can specify parameters when starting dropbear?

On my router I have turned off Dropbear in the WebUI and then enabled it manually. I find it most reliable this way.

Example

Create this files in /jffs/dropbear folder.

authorized_keys
dropbear_dss_host_key
dropbear_ecdsa_host_key
dropbear_rsa_host_key
loginprompt

/jffs/scripts/services-start

#!/bin/sh

# begin accepting Dropbear logins
source /jffs/home/dropbear-start

# add cron job:  check dropbear every 5 mins
#cru a id "minute(0-59) hour(0-23) day(1-31) month(1-12) weekday(0-6 with 0=Sunday) command"
/usr/sbin/cru a CheckDropbear              "*/5   *  *    *  *  /jffs/home/dropbear-start"

/jffs/home/dropbear-start

#!/bin/sh
local DROPBEAR_CMD="/usr/bin/dropbear -p 65123 -I 86400 -s -j -k -b /jffs/dropbear/loginprompt"
local DROPBEAR_PID=$(/bin/echo $(/bin/ps w | /bin/grep -i "$DROPBEAR_CMD" | /bin/grep -v grep) | /usr/bin/cut -f1 -d' ')

if [ -z "$DROPBEAR_PID" ]; then
  /usr/bin/killall dropbear
  /bin/sleep 1
  /bin/rm -rf /root/.ssh
  /bin/ln -sf /jffs/dropbear /root/.ssh
  /bin/rm -rf /etc/dropbear
  /bin/ln -sf /jffs/dropbear /etc/dropbear
  /bin/chown -R $(/usr/sbin/nvram get http_username):root /jffs/dropbear
  /bin/chmod 700 /root/.ssh
  /bin/chmod 600 /root/.ssh/*
  $DROPBEAR_CMD
fi
