a340db5e76 wct4xxp: Reduce stack usage in oct612x API. 
Reduce the stack usage by replacing the mOCT6100_RETRIEVE_NLP_CONF_DWORD
and mOCT6100_SAVE_NLP_CONF_DWORD macros with functions. Some compilers
do a better job of optimizing the local variables declared in those
macros than others.

For example, with gcc 4.3.0, running

]# make stackcheck | grep Oct6100 | head -n 20 | sed -e 's/^0\S* //g' | uniq

bf3fe05dfb wct4xxp: Moving the transmit short detection behind debug module param. 
This needs some more testing before it's on by default.  If the card is
otherwise functioning, these messages may be confusing to the user.  If
the card is not functioning, the driver can be reloaded with debug to
check for this condition.
