[Qemu-block] nbd max request size

[Peter Lieven]

Hi,

while talking to a very old NBD server from a recent Qemu Version i noticed 
that the max request size for NBD
changed from 1MB to 32MB somewhen in the past with commit

commit 2d8214885942becb8f4371a66d6f8c9a9580108a

    nbd: support large NBD requests

Is it possible to detect in the client which NBD server is running and adjust 
the limits accordingly?

Thanks,
Peter
