This causes e.g. "ssh nosuchname" to print "No address associated with
hostname", which is correct, rather than "hostname nor servname
provided, or not known", which is not.
kill and sh were merged so that the shell (for trap -l) and
kill (for kill -l) can use the same routine, and site that function
in the shell, rather than in kill (use the code that is in kill as
the basis for that routine). This allows access to sh internals,
and in particular to the posix option, so the builtin kill can
operate in posix mode where the standard requires just a single
character (space of newline) between successive signal names (and
we prefer nicely aligned columns instead)..
In a SMALL shell, use the ancient sh printsignals routine instead,
it is smaller (and very much dumber).
/bin/kill still uses the routine that is in its source, and is
not posix compliant. A task for some other day...
The SYNOPSIS for "readonly -q" cannot have the -q be
optional ... Also harmonise the output appearance with
that of the export command.
wiz: have at it...
readonly -q VAR...
readonly -p VAR...
export -q [-x] VAR...
export -p [-x] VAR...
all available only in !SMALL shells - and while here, limit
"export -x" to full sized shells as well.
Also, do a better job of arg checking and validating of the
export and readonly commands (which is really just one built-in)
and of issuing error messages when something bogus is detected.
Since these commands are special builtin commands, any error
causes shell exit (for non-interactive shells).
- when call dosoftints from cpu_idle, interrupts should be disabled.
rarely, lwp stack had been exhausted when high interrupts.
reported by alnsn@. thanks.
and smallkern, there is little interest installing them by default,
rather they can be downloaded from www. It's better this way.
While here add NVMM(4) in "SEE ALSO".
- Rename wm_smbustopci() to wm_init_phy_workarounds_pchlan(). It will also
called when resume.
- Call wm_phy_resetisblocked() after PHY reset in
wm_init_phy_workarounds_pchlan() to wait for the PHY to quiesce to an
accessible state.
- Add new wm_resume_workarounds_pchlan() function and use it in wm_resume().
This workaround is only for PCH2 and newer.
- Don't call wm_disable_aspm() neither in wm_attach() nor in wm_resume()
but in wm_reset().
- Do some initialization in wm_resume() when IFF_UP is NOT set.
- Don't continue when it failed to acquire semaphore in wm_ulp_disable().
- Add comment.
In particular, add a readonly test to detect the bug that was just fixed...
(but there is more than that one added here).
Also, allow zsh to run more of these tests than it did, what is a builtin
command most places (including in POSIX) can be a reserved word in zsh!
var=foo; readonly var=new
now fails.
If var was already set, an attempt to make it readonly, and assign it
a new value at the same time, failed - the readonly flag was set too soon.
Pointed out by Martijn Dekker (thanks).
Also, while here, add a couple of comments.
mentioned repeatedly as a non-MP-safe driver that is hard to maintain,
and no one is taking care of it.
LMC was removed from OpenBSD three years ago, and from FreeBSD a few
months ago.
Now, we have M_CSUM_TSOv[46] bit in ifp->if_csum_flags_tx when
TSO[46] is enabled for the interface. So we can simply check
whether TSO[46] is required in a packet but missing in the
interface by (sw_csum & M_CSUM_TSOv[46]).
Note that this is a very rare case where TSO[46] is suddenly
turned off during a packet passing b/w TCP and IP.

For rump kernels, if_capabilities for shmemif(4) can be specified
by environmental variable RUMP_SHMIF_CAPENABLE:
setenv RUMP_SHMIF_CAPENABLE 0x7ff80 (all offload)
setenv RUMP_SHMIF_CAPENABLE 0x6aa80 (all TX)
setenv RUMP_SHMIF_CAPENABLE 0x15500 (all RX)

Handle TX offload in software when a packet is sent via
bridge_output(). We can send it as is in the following
exceptional cases:
For unicast:
(1) When the destination interface is the same as source.
(2) When the destination supports all TX offload options
specified in a packet.
For multicast/broadcast:
(3) When all the members of the bridge support the specified
TX offload options.
For (3), add sc_csum_flags_tx flag to bridge softc, which is
logical AND b/w capabilities of TX offload options in member
interface (ifp->if_csum_flags_tx). The flag is updated when a
member is (i) added to or (ii) removed from a bridge, or (iii)
if_csum_flags_tx flag of a member interface is manipulated via
ifconfig(8).
Turn on M_CSUM_TSOv[46] bit in ifp->if_csum_flags_tx flag when
TSO[46] is enabled for that interface.

Add ether_sw_offload_[tr]x: handle TX/RX offload options in software.
Since this violates separation b/w L2 and L3/L4, new files are added
rather than having the routines in sys/net/if_ethersubr.c.
OK msaitoh thorpej
