Re: FW: Afpacket daq-2.0.1 snort

[Jaime Nebrera <jnebrera () redborder org>]

Hi Anshuman,

We don't know for that card in particular, but in general the technology
has gone through various steps:

Gen 1.- Non software controlable. Bypass is enabled either due to power
failure or missed watchdog

Gen 2.- Software controlable, but using a modified card driver. This in
general is complex to maintain

Gen 3.- Software controlable, by specific bypass driver, letting the card
controller driver untouched

We use another manufacturer cards (Silicom) and Gen 3 which in essence us
to do whatever we want with them and keep card drivers updated through CLI
orders. As for IM I can't advise on how they do but guess would be similar
(but believe your card is old thus might be Gen 1 or 2)

Regards
