Hello,
I have a couple of questions regarding l2cap_options.
I have posted the main question on Stackoverflow:
https://stackoverflow.com/questions/50380020/where-is-the-documentation-of-l2cap-options
I would like to play with the options of l2cap. But there is no
documentation even in the kernel header. Where can I find a description
of the different fields?
On my system, I see:
omtu:0 imtu:672 flush_to:65535 mode:0 fcs:1 max_tx:3 txwin_size:63
I don't understand why omtu is different from imtu. What are the other
options?
Also, on this page
https://people.csail.mit.edu/albert/bluez-intro/x95.html#l2cap-and-udp,
it says that there are three policies possible: never retransmit,
default, drop and move. How do I select the policy?
I was guessing that the "default" is to have flush timeout of 0 and the
"drop and move" after x ms is just to put a specific timeout (knowing
that 1279ms = 0x7ff * 625us). Am I right? But then how do you select
"never retransmit"?
