[B.A.T.M.A.N.] Reading batman-adv buffer

[Krishnathiepan Rasanayagam]

Hi all,

Does anyone knows how we can read data from batman-adv transmission
buffer. before it transmits. Can we change the buffer ?
Any details about the way batman-adv is using the buffer is valuable.
Please update me.

thanx in advance

There is no buffering taking place in batman-adv (unless you use network 
coding). It simply takes whatever comes in from either neighboring nodes 
or the virtual interface, and puts it in the relevant queue *outside* 
batman-adv. For outgoing (or forwarded) packets this is the tx-queue of 
the underlying interface (e.g. the one that is controlled with 'ip link 
set dev wlan0 txqlen'). For incoming packets, it is the rxqueue of the 
virtual interface (bat0), if one such exists.

Hope this helps!
