commit 6e1b61075c183daad7a38733a38ca960abc3ed0d
Author: Matthew Dillon <***@apollo.backplane.com>
Date: Thu Nov 1 19:06:14 2018 -0700
boot - Handle tftp block overflows
* Properly truncate the block number when comparing against the
incoming packet. TFTP only implements 16-bit block numbers.
This allows the boot loader to access files larger than 32MB
via TFTP.
* Twiddle every 256 reads instead of every 16.
* Note that TFTP is not really a suitable protocol for loading the
kernel because the ELF loader seeks past the debug info which
can be well over a hundred megabytes in order to get to the syms.
NFS is preferred.
