23 * MAC address typo fixed. 010417 --ro
24 * Integrated. 020301 --DaveM
25 * Added multiskb option 020301 --DaveM
26 * Scaling of results. 020417--sigurdur@linpro.no
27 * Significant re-work of the module:
31 * * Allow configuration of ranges, like min/max IP address, MACs,
32 * and UDP-ports, for both source and destination, and can
35 * * Place 12-byte packet in UDP payload with magic number,
37 * * Add receiver code that detects dropped pkts, re-ordered pkts, and
38 * latencies (with micro-second) precision.
40 * --Ben Greear <greearb@candelatech.com>
50 * --ro
52 * Sept 10: Fixed threading/locking. Lots of bone-headed and more clever
53 * mistakes. Also merged in DaveM's patch in the -pre6 patch.
54 * --Ben Greear <greearb@candelatech.com>
56 * Integrated to 2.5.x 021029 --Lucio Maciel (luciomaciel@zipmail.com.br)
64 * also the thread checks the thread->control which is used for inter-process
76 * /proc/irq/XX/smp_affinity so TX-interrupts gets bound to the same CPU.
77 * --ro
80 * memleak 030710- KJP
82 * First "ranges" functionality for ipv6 030726 --ro
86 * Fixed unaligned access on IA-64 Grant Grundler <grundler@parisc-linux.org>
