[U-Boot] [PATCH v2] net: Add bootfile in DHCP Request

[amessier.tyco at gmail.com]

From: Alexandre Messier <amessier at tycoint.com>

Add the bootfile name in the DHCP Request packet, in addition
to it already being sent in the DHCP Discover.

This is needed by some DHCP servers so that the bootfile name is
properly returned by the server to the client in the DHCP Ack, as
expected by U-Boot.

Changes since v1:
 - Addressed Joe Hershberger's comment: Removed the config option, always
   send the bootfile name.
 - Removed from patch series. v1 was in a series, but now the patch
   stands alone.

v1 can be found here:
