Are you augmenting an existing design, where you just need to add the 
web / telnet front-end?  If so, the Lantronix XPort and Digi ME are a 
turnkey platform built into an RJ-45 jack - MCU, RAM, Flash, MAC, PHY, 
crystal, etc.  At about $50 ea, there is no smaller solution.

Add one to your board and use either serial or GPIO from the jack to 
your main MCU.  The units can be scripted to front-end a CLI or a basic 
serial command interface.

However, if you're looking to use this Ethernet MCU as your primary 
processor, then others are probably better suited.

But consider the total cost involved, including development cost - you 
may find that a smaller, cheaper primary MCU with one of the Digi or 
Lantronix is cheaper / simpler overall.

We run a multithreaded web server on a Philips LPC2106 (60 MHz
ARM, 128k Flash, 64k RAM on chip) with an external Ethernet
chip (RTL8019AS or AX88796). Cheap, fast, small.

If you need more web page space, you could use the LPC2138
(60 MHz ARM, 512k Flash, 32k RAM on chip).

For more details of the stack, see:

Depending on your spec/cost/time tradeoffs, there is no
need for Linux and "big" hardware, providing that the
software is designed for smaller systems.
