[Discuss-gnuradio] Question regarding usrp2_basic.cc

[Mattias Kjellsson]

Hi,

I have been browsing the sources for the usrp2, so that I'm familiar 
enough with the code when the new usrp2 comes. I have a million 
questions regarding it, but there is one simple one for starters. At 
line 70 in my usrp_basic.cc (svn-rev 8510), i have the following line of 
code:

#define MAX_PKTLEN 1512 //biggest thing USRP2 can swallow
                                              // (14-byte ethernet hdr 
+ 1500 byte payload)

My question is; Is there something I have missed regarding the packets 
and their format, is this a typo, is it something that everybody else 
knows (for instance -"you always have to pad the packets with one byte" 
or similar), or something completely  different than the above suggestions?

Cheers
