Package: pxe-kexec
Version: 0.2.4-3
Severity: wishlist
pxe-kexec is a TFTP client.
It's good for TFTP clients to:
1. default to 512b block size, for compatibility.
2. support greater block sizes, for speed.
AFAICT pxe-kexec does (1) but not (2).
In the example below, you can see that increasing the block size lets
curl download from dnsmasq two-and-half times faster!
root@het:~# curl --tftp-blksize 512 >/dev/null
tftp://prisonpc/images/inmate/{vmlinuz,initrd.img}

I want to keep using pxe-kexec because it's handy for parsing pxelinux.cfg
files.
But I also want it to finish quicker!
Can this be patched into pxe-kexec?
