conditional on a particular configuration method.
The global flags "nfs_boot_rfc951" and "nfs_boot_bootparam" control
independantly if the functions are actually called. (Previous meaning
of "nfs_boot_rfc951" was "either-or".)
gateway=server:255.255.255.0 because that is the perferred format,

(Copied ip_convert here from the libsa code.)
whether we get it off the wire. An nfsiod might have been busy with
it, and finished while we were waiting for it in nfs_getcacheblk, so
we need to check for EOF again no matter what.
the directory cache as translation table. See nfs_subs.c for comments.
Makes the code a bit more complex to look at than I would have liked,
but doesn't affect the speed of the default behavior.
* Optimize caching behavior a bit when buffers are invalidated.
* Save some RPCs in readdir operations by not bothering if there is
a small amount left to do to fill the buffer. It'll be done in the
next RPC with a larger chunk anyway. Wastes a bit of buffer space
but is faster.
* Make n_vattr an allocated vattr struct. This avoids nfsnode bloat,
and is friendlier to the malloc routines.
directory cookie that may be thrown back at us from userspace, up
to a size limit. Fixes double entry problem.
* Split flags for internal and external use in the NFS mount structure.
* Fix some buffer structure fields that weren're being used correctly.
* Fix missing directory cache inval call in nfs_open.
* Limit on NFS_DIRBLKSIZ no longer needed, bumped to the more reasonable
value of 8k.
* Various other things that I forget, all related to the dir caching
somehow, though.

Don't increment xid between retries anymore, it is not required and
it increases the response time in case of a slow server.
Use common code with bootparam boot.

2. Comment out unneeded NFS swap related stuff.
Closes PR kern/3918.
From Olaf Seibert <rhialto@polder.ubc.kun.nl> (PR 3687)
* Make an attempt to check the maximum filesize before attempting
a write to the server, as write RPCs will typically happen
asynchronously, and the process will not see the error.
Fixes problems with unexpectly truncated files at 4G
* Pass up errors in nfs_writerpc correctly
the server code would always skip all dir entries for a readdirplus
operation. To avoid endlessly retrying clients, try VFS_VGET first,
and it it fails, return NFSERR_NOTSUPP so that client will fall
back to normal readdir operations.
In readdirplus, don't keep such pointers but store the file attributes
in a variable instead until they are needed. Change nfsm_loadattr*
a bit so it can accept a direct pointer to an nfs_fattr structure.
architectures), truncate them intelligently instead.
The truncation is done centralized in vnode_pager.c.
This prevents from wrap-over effects when parts of large (>2^32 byte) files
are mmapped.
Don't allow to mmap above the numerical range of vm_offset_t.
This is considered a temporary solution until the vm system handles the
object sizes/offsets more cleanly.

it translates the '%' escapes (URL-style) in the same case. Also,
make nfsrv_fhtovp convert the public filehandle to the vp of the
publicly exported filesystem, as stored in the nfs_pub structure.
