    Wait a maximum of 300 seconds for network send/recv in libsa
    
    The reason for this change is that currently, a send/recv
    takes many hours to time out.
    This is suboptimal in the bootloader because it means for example
    that NFS will take hours to fail before allowing subsequent access
    methods such as gzip to be tried.
    
    Setting MAXWAIT to 300 seconds (5 minutes) still allows slow
    connections of 1Mb to be used to download a 30MB kernel file.
    
    (cherry picked from commit d5cee48f3e65662051e15c85e4fc1841d72977fe)
