Subject: Extended presence mask ignored in injected frame
Date: Mon, 28 Feb 2011 10:32:32 +0100 [thread overview]
Message-ID: <4D6B6BB0.3070500@create-net.org> (raw)
Hi,
I'm injecting some traffic using the Click modular router. The radiotap
header that I'm building contains four presence masks. In the first three
mask the bit 31 is set to 1 while the last masj sets the bit 31 to 0.
The problem is that only the first block is parsed by the kernel while
the other
are ignored more precisely -ENOENT is returned when the last bit of the
first
presence mask is found. Basically since in the second to forth blocks I'm
specifying RATE and DATA_RETRIES fields I was expecting this fields to be
processed multiple times in the tx.c file. However this is not happening and
only the first occurrences of RATE and DATA_RETRIES fields are processed.
Is anybody using frame injection with multiple presence masks and has faced
the same issue? The driver I'm using is ath5k.
R.
