Kernel needs MTU patch to properly support EVDO

[IFRFlyer]

3G high-speed cellular wireless cards, such as the internal 5720 and PCMCIA 5740 for Verizon Wireless, can be supported under Breezy and Dapper. However without an MTU patch raising the minimum size of MTU in the kernel, speeds are limited to 109Kbps or so. With the MTU patch, which is too complex for me to do, speeds of >1Mbps are possible and routine speeds of 600kbps are easily attained. Because most new business laptops from Lenovo, HP, Dell and others have or will very soon have these internal cards, I think the community would be very well served if this patch could be included in the Dapper kernel or at least a how-to posted. I'd be willing to write the how-to if an engineer or programmer were to work with me on the procedures. Information is available here:

and I can find more if anyone needs help locating more specific information. Thanks in advance

Sam thanks. Are you saying that the thing has been fixed as of that or that
I should download and compile that?

Thanks
Nick

(The adjustment made simply means the bug report is now assigned to the correct source package.)

Two more data points:

This wish/bug has had no activity for a considerable period. This is a check to see if there is still interest in investigating this wishlist report.
Marking "incomplete" as it's well time for this to either pick-up or dropped.
