* Improve acquisition of transaction labels.Hidetoshi Shimokawa2007-07-151-20/+16
| | | | | | | | | | | - Keep last transaction label for each destination. - If the next label is not free, just give up. - This should reduce CPU load for TX on if_fwip under heavy load. Approved by: re (hrs) Notes: svn path=/head/; revision=171457
* Fix a bug of retrieving configuration ROM.Hidetoshi Shimokawa2007-07-081-2/+2

| | | | | | | | | | | for unknown events. A number of modules return EINVAL in this instance, and I have left those alone for now and instead taught MOD_QUIESCE to accept this as "didn't do anything". Notes: svn path=/head/; revision=132199
