Hal creates shmem before waiting for SoftPLL to lock. By this other programs
waiting for HAL's shmem can start.
Please note that after this fix PPSi does not create shmem before lock.
It waits for HALs minipc server to be ready.

Before shmem is created, read hal mode first.

Function hal_port_get_exported_state, fills structure hal_port_state with data
that are not available in SHM. It just assigns defines.
These defines are private to HAL, and assignment should be done in HAL.

Similar problem is for wrpc. There is a wrapper function that pretends to be
HAL. All HAL info should be filled in that function.

Fields added:
--uint32_t clock_period;
--uint32_t t2_phase_transition;
--uint32_t t4_phase_transition;

Additionally updated wrs_dump_shmem.c to dump new fields and the version number
of HAL SHM.

delta_tx and delta_rx in the SFP information are differences from
the values in the "calibration" SFP model. Thus they are signed
not uint32_t.  Fortunately nobody used negative values so far.

I also renamed the fields, to ensure the compiler would find all uses.

The commit also syncs headers to ppsi, including the changes that
happened here but were irrelevant to there.

Signed-off-by: Adam Wujek <adam.wujek@cern.ch>

bug introduced in c45f9161

.

The new check for dotconfig params was added after setting
port->in_use to 1.  Thus, at each loop, the hal was calling

   ioctl(6, SIOCGIFFLAGS, {ifr_name="", ???}) = -1 ENODEV (No such device)

but that ENODEV was after a call to modprobe for the "" interface.
Actually this command:

    /sbin/modprobe -q -- netdev-

By means of /sbin/modprobe being the string in /proc/sys/kernel/modprobe .
But modprobe is busybox, so over NFS we had a zillion stat() accesses
for ld.so, uclibc.so and busybox.

Thanks Adam for noting the NFS traffic increase at that commit.

If no specific alpha is passed in configuration, we can't even know if
it is positive or negative. 0 is a safe default, and it is the exact

This commit uses dot-config (previous commit), in exactly the same
way as previous code. No change in behaviour is there, as confirmed
by looking at shared memory values.

As a side effect, the ports as listed in shared memory
(wrs_dump_shmem) are in the right order instead of random order
(this was due to use of lua's hash functions).

Signed-off-by: Alessandro Rubini <rubini@gnudd.com>

This has no effect on the code functionality.

Even if it affects libwr, this is a hal-only change.  The functions
in libwr that the hal itself uses, now receive a pointer to ports[],
which is thus back a static pointer within wrsw_hal/hal_ports.c.

This change allows moving the RPC queries to be shared memory lookups,
by using the ports[] pointer in the client; so both the client and
the server can access the same shared mamory using libwr functions.
