edavis d80c749b8d Fixed a tx watchdog chip reset that could occur on mostly idle links.
Fixed various link related issues and 10GBaseT is now linking properly.
Modified the types for the driver tunables to be consistent with the sysctl APIs.

* congestion managment port init api description
* the api works as follows:
* the driver should pass the cmng_init_input struct, the port_init function
* will prepare the required internal ram structure which will be passed back
* to the driver (cmng_init) that will write it into the internal ram.
*
* IMPORTANT REMARKS:
* 1. the cmng_init struct does not represent the contiguous internal ram
* structure. the driver should use the XSTORM_CMNG_PERPORT_VARS_OFFSET
* offset in order to write the port sub struct and the
* PFID_FROM_PORT_AND_VNIC offset for writing the vnic sub struct (in other
* words - don't use memcpy!).
* 2. although the cmng_init struct is filled for the maximal vnic number
* possible, the driver should only write the valid vnics into the internal
* ram according to the appropriate port mode.
