My guess (untested) would be per Section 8.4 in
https://tools.ietf.org/html/rfc2132
with the leading Code=43 and Len=n
octets possibly prepended by the software.

And a bit of idle searching [1] suggests that perhaps (untested)
only the trailing "Raspberry Pi Boot" string is required.

Also I notice that 50:58:45 spells "PXE".
