Details:
I try to use grub as general PXE solution for UEFI systems, but fint it
impossible to chainload to efi files located on Windows TFTP servers, since
they operate with back slashes in their paths instead of forward slashes.
For example:
set root(tftp,192.168.2.3)
chainloader smsboot\\x64\\wdsmgfw.efi
or
chainloader (tftp,192.168.2.3)smsboot\\x64\\wdsmgfw.efi
both result in "error: invalid EFI file path".
Manual "get smsboot\\x64\\wdsmgfw.efi " with any tftp client works.
Moving the file over to a *ix server and use backslash works, it will load the
file.
In general, I think it is wrong to validate path strings on TFTP servers.
