Richard Cochran 1f2c9de982 clockadj: remove useless clockid parameter.
The clockid parameter to the function to get the system clock's maximum
adjustment is redundant, so let us just remove it.

Jacob Keller 76e10e95fb ptp4l: Use poll() instead of a try-again loop
This patch modifies sk_receive in order to use poll() on POLLERR instead of the
tryagain loop as this resolves issues with drivers who do not return timestamps
quickly enough. It also resolves the issue of wasting time repeating every
microsecond. It lets the kernel sleep our application until the data or timeout arrives.

This change also replaces the old tx_timestamp_retries config value with
tx_timestamp_timeout specified in milliseconds (the smallest length of time poll
accepts). This does have the side effect of increasing the minimum delay before
missing a timestamp by up to 1ms, but the poll should return sooner in the
normal case where a packet timestamp was not dropped.

This change vastly improves some devices and cleans the code up by simplifying a
race condition window due to drivers returning tx timestamp on the error queue.

[ RC - removed the unused 'try_again' variable. ]

Richard Cochran 2ec3829bd4 Apply utc offset correction even when free running.
When using software time stamping and a free running clock, the
statistics appear to be off by the TAI offset. This patch fixes the
issue by setting the internal UTC timescale flag in such cases.

Due to a bug in older kernels, frequency reading may silently fail and

Libor Pechacek 0367bb5f1b Distinguish between ignored and malformed packets
When there is a peer speaking PTPv1 in the network we want to silently ignore
the packets instead of flooding system log with error messages.  At the same
time we still want to report malformed packets.  For that we reuse standard
error numbers and do more fine-grained error reporting in packet processing
routines.

Richard Cochran 1ff9d0d0d2 Align the message buffer to eight bytes.
The 'struct ptp_message" includes a 64 bit integer field, ts.pdu.sec,
and this must be aligned to an eight byte boundary for armv5 machines.
Although the compiler puts the field at the right offset, we spoil this
by packing the struct with 20 bytes of head room. This patch fixes the
issue by realigning the message buffer.
