net: Fix TftpStart() ip:filename bug
The TftpStart() function modifies the 'BootFile'
string when 'BootFile' contains both an IP address
and filename (eg 1.2.3.4:/path/file). This causes
subsequent calls to TftpStart to incorrectly parse
the TFTP filename and server IP address to use.
For example:
=> tftp 0x100000 10.52.0.62:/home/ptyser/non_existant
Speed: 100, half duplex
Using eTSEC1 device
TFTP from server 10.52.0.62; our IP address is 10.52.253.79
^^^^^^^^^^ CORRECT
Filename '/home/ptyser/non_existant'.
^^^^^^^^^^^^^^^^^^^^^^^^^ CORRECT
Load address: 0x100000
Loading: *
TFTP error: 'File not found' (1)
Starting again
eTSEC2: No link.
Speed: 100, half duplex
Using eTSEC1 device
TFTP from server 10.52.0.33; our IP address is 10.52.253.79
^^^^^^^^^^ WRONG
Filename '10.52.0.62'.
^^^^^^^^^^ WRONG
Load address: 0x100000
Loading: *
TFTP error: 'File not found' (1)
Starting again
TftpStart() was modified to not modify the 'BootFile' string.
