[ns] Why do I receive Invalid MAC Control subtype?

[Sanaz]

Dear all,
Can somebody tell me why exactly the Invalid MAC Control subtype message
is being produced by mac-802_11 module? 
I have changed the ACK packet structure, and have not touched MAC header.
This error message that always appears only when I increase the number of
nodes in the network. And this makes me believe that my modifications should
not be the source of the problem.
When I tracked down the problem, I understood that the packet had a correct
type and subtype before the defer timer being set, but somehow, the header
becomes null when the defer timer expires and MAC goes to check_pktCTRL
subroutine. Any idea why this message was originally put in the check_pkt*
subroutines? Or any specific reason why the header might become null?
Any kind of help is really appreciated.

Regards,
Sanaz

[ns] Need expert's help for MAC-802.11 module.

[Sanaz]

Hello,

I am new with NS2. I use MAC-802_11 as my reference MAC, and I need to
modify it to fit my needs. 

Some of my ACK packets need to be processed by 2 specific nodes, instead of
one. In 'Mac802_11::recv_timer' function, packets are dropped based on their
receiver address in MAC802.11 header not the address in 'ack_frame',
therefore I need to add an address variable to my new header. It seems that
'Mac802_11::hdr_src' and 'Mac802_11::hdr_dst' functions are responsible for
setting address variables in MAC802.11 header. My problem is that I can not
find any other function calling them. Can anybody tell me what invokes these
2 functions?

Any help is really appreciated.
Regards,
Sanaz
