[Bug 1246236] Re: pxe boot from maas fails due to time out

[Christian Reis]

Static ARP did not help.

Setting the MTU to 1200 caused pxelinux.0 to fail transferring with
similar, but different behaviour:

12:12:50.699971 IP 10.0.0.12.2071 > 10.0.0.1.tftp:  32 RRQ "pxelinux.0" octet blksize 1456 
12:12:50.773393 IP 10.0.0.1.59263 > 10.0.0.12.2071: UDP, length 15
12:12:50.773775 IP 10.0.0.12.2071 > 10.0.0.1.59263: UDP, length 4
12:12:50.774211 IP 10.0.0.1.59263 > 10.0.0.12.2071: UDP, length 1404
12:12:50.774226 IP 10.0.0.1 > 10.0.0.12: udp
12:12:51.774349 IP 10.0.0.1.59263 > 10.0.0.12.2071: UDP, length 1404
12:12:51.774387 IP 10.0.0.1 > 10.0.0.12: udp
12:12:54.775554 IP 10.0.0.1.59263 > 10.0.0.12.2071: UDP, length 1404
12:12:54.775592 IP 10.0.0.1 > 10.0.0.12: udp

I'm curious as to why the blksize is set at 1456 by pxelinux.
