svn commit: r342282 - head/stand/libsa

New Revision: 342282
URL: https://svnweb.freebsd.org/changeset/base/342282

Log:
  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.
