From: "Peter E. Berger" <pberger@xxxxxxxxxxx>
The io_ti driver fails to download firmware to Edgeport devices such as
the EP/416. One of the problems is that the default 1 second timeout
in ti_vsend_sync() is insufficient for download operations. This patch
increases the download timeout to 10 seconds.
