Revision 65deeed7b34bc5b8d3cbff495e8fa2ae7b563480 authored by Greg Rose on 24 March 2010, 09:35:42 UTC, committed by David S. Miller on 26 March 2010, 18:56:00 UTC 
ixgbevf: Fix signed/unsigned int error
 
In the Tx mapping function if a DMA error occurred then the unwind of
previously mapped sections would improperly check an unsigned int if
it was less than zero.  Changed the index variable to signed to avoid
the error.
