The patch has bugs. The least of them is memory leak. Please use ML for patches, not bugtracker.

Uploaded a new patch.  Changes to bootp.c have been simplified and net_get_dhcp_option documentation has been updated.

(file #32481)

You do not really need endian conversion. Just print each byte directly.

grub_printf("%d.%d.%d.%d", ptr[0], ptr[1], ptr[2], ptr[3])

Please update documentation too.

There are a few ip addresses, not automatically set to variables, that may be needed in a grub config (such as netmask and default router).  These may be retrieved with net_get_dhcp_option, but only as the decimal or hex representation of the 32-bit value.  I have included a patch that adds a new format specification 'ip' to net_get_dhcp_option, allowing values to be displayed/saved as ip strings.
