The TFTP file system code has been updated so you can have more than one
instance active at once. The mount command for the TFTP file system is:

 mount -t tftpfs host:/dir /target

Where the host can be an IP address or host name. Currently the code uses
gethostbyname which is not reenterant. TFTP servers may allow an absolute path,
how-ever for security this is often rejected. You can handle both absolute and
relative paths. For an absolute path where all accesses must be under /tftpboot
on a server called 'server' use:

 $ mount -t tftpfs server:/tftpboot /boot

To read a file called 'one' under /tftpboot on 'server' do:

 $ cat /boot/one

For a relative path on 'rtems.org' of 'ftp' use:

 $ mount -t tftpfs rtems.org:ftp /rtemsftp

To read a file called 'Welcome' you would:

 $ cat /rtemsftp/Welcome

You can also reference the top of the TFTP path on a relative server with:

 $ mount -t tftpfs server: /server

Note, no need for the path component.
