* beyond that doesn't actually implement PTP.
*
* Outgoing packets are time stamped with SO_TIMESTAMPING with or

*
* Incoming packets are time stamped with SO_TIMESTAMPING with or
* without hardware support, SIOCGSTAMP[NS] (per-socket time stamp) and
* SO_TIMESTAMP[NS].

/* NOTES:
This driver was written for the Dynalink IS64PH ISDN TA, based on two
Siemens chips (HSCX 21525 and ISAC 2186). It is sold in the Netherlands.
model numbers found on (my) card:
IS64PH, TAS100H-N, P/N:89590555, TA200S100045521
chips:
Siemens PSB 21525N, HSCX TE V2.1
Siemens PSB 2186N, ISAC-S TE V1.1
95MS14, PNP
plug-and-play info:
device id "ASU1688"
vendor id 0x88167506
serial 0x00000044
i/o port 4 byte alignment, 4 bytes requested,
10 bit i/o decoding, 0x100-0x3f8 (?)
irq 3,4,5,9,10,11,12,15, high true, edge sensitive
At the moment I'm writing this Dynalink is replacing this card with
one based on a single Siemens chip (IPAC). It will apparently be sold
under the same model name.
This driver might also work for Asuscom cards.

This function computes the length of the initial part of
the string pointed to by <[s1]> which consists entirely of
characters <[NOT]> from the string pointed to by <[s2]>
(excluding the terminating null character).
RETURNS
<<strcspn>> returns the length of the substring found.
PORTABILITY
<<strcspn>> is ANSI C.
<<strcspn>> requires no supporting OS subroutines.
