I believe "Giant" is a reference to the a portion of the internal task 
scheduler's universal lock in FreeBSD's kernel and can be 
enabled/disabled by using the ADAPTIVE_GIANT directive in the kernel 
config file.

It may also be a fault in the way that either the driver for your 
network card is written or lack of support which is causing that issue 
to come up, as well.

Here's a document on the supposed "Giant Lock", by the world famous (or 
at least FreeBSD famous ;).) Greg Lehey: 
<http://www.lemis.com/grog/SMPng/Singapore/paper.pdf>, and if you
google "Giant deferred", you'll find a few documents that I'm referring 
to in the *BSD world.
