I am trying to digest some things in the carl9170 firmware.
Many routines are coded to look like interrupt handlers, but the
code seems to be entirely polled ?
Am I correct there ? If so do you know if the AR9170-fw code or
something else might show an example of interrupt handling for the
AR9170. I must have tx complete interrupts.
Next there are remarks throught the driver and firmware regarding
cookies.
I think a cookie is a u8 that uniquely identifies a packet - is
that correct ?
In the firmware there is a remark somewhere that suguests that the
cookie AND something else are needed - is that correct or is the cookie
sufficient ?
Thank you.
