Subject: Reflex jamming is now absurdly accurate and reliable.
X-Git-Url: http://git.rot13.org/?p=goodfet;a=commitdiff_plain;h=b0672fbb55953e2530caed3e2f37ed2ac938a97c

Reflex jamming is now absurdly accurate and reliable.
Backoff timings allow for long packets to be destroyed while short packets are unharmed.
