Miroslav Lichvar 3012cf0540 Add option to set maximum frequency adjustment.
The option sets an additional limit to the hardware limit. It's disabled
if set to zero. The default is 900000000 ppb.

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. ]

Delio Brignoli da594e78d9 Make the fault reset interval a per-port configuration parameter.
A timeout of 15 seconds is not always acceptable, make it configurable.

By popular consensus, instead of using a linear number of seconds, use
the 2^N format for the time interval, just like the other intervals in
the PTP data sets. In addition to numeric values, let the configuration
file support 'ASAP' to have the fault reset immediately.

[RC - moved the handling of special case tmo=0 and added a break out
      of the fd event loop in case the fds have been closed.
    - changed the linear seconds option to log second instead.
    - changed the commit message to reflect the final version. ]

Miroslav Lichvar a373805b6d ptp4l: increase default tx_timestamp_retries to 100.
It seems with some cards the current default of 2 is too small, increase
the number to prevent users from having to investigate the EAGAIN error
messages.
