[openib-general] link to the ipoib charter page pointed by the kernel IB docs is broken

[Or Gerlitz]

Hi Hal,

I think you were involved in setting/updating the pointers from the 
IPoIB kernel docs to the IETF website...

I see now that the link pointed by drivers/infiniband/ulp/ipoib/Kconfig
and Documentation/infiniband/ipoib is broken, i can find many copies of 
it eg http://mirror.switch.ch/ftp/doc/ietf/ipoib/ipoib-charter.txt but
the original one http://www.ietf.org/html.charters/ipoib-charter.html 
does not work.

Or.
