In the file linuxcniapi.c, there are 2 references to skb->stamp (one in line 452, one in line 315). Now in the Linux Kernel 2.6 this has been changed to skb->tstamp. This needs to be fixed in order to get rid of the compilation errors. [ubuntuforum]
I just opened that file in the Cisco client source code… modified stamp to tstamp… and it compiled perfectly.
