Unable to get any http requests: Unable toretreive netstg2.imgfile

[Shabazian, Chip]

The reason you can get an IP and PXEboot is because the NIC is up for
more than 30 seconds, which gives the switch time to negotiate with the
NIC and turn up the port.  When anaconda starts, it recycles the NIC (to
load the driver).  If you have portfast issues, anaconda will timeout
before your switch makes the port live.

Ananacoda will also recycle the NIC one more time after it gets the
ks.cfg, but that one never causes portfast timeout issues.

What I don't understand is how the BIOS and pxelinux can both get an IP
address, and Anaconda can't.

Have you tried using IPAPPEND instead of ip= on the kernel parameters. 
Read syslinux.doc for clarification.
