* Nov 26, 1997 Jaspreet Singh Added 'load_sharing' structure. Also added
* 'devs_struct','dev_to_devtint_next' to 'sdla_t'
* Nov 24, 1997 Jaspreet Singh Added 'irq_dis_if_send_count',
* 'irq_dis_poll_count' to 'sdla_t'.
* Nov 06, 1997 Jaspreet Singh Added a define called 'INTR_TEST_MODE'
* Oct 20, 1997 Jaspreet Singh Added 'buff_intr_mode_unbusy' and
* 'dlci_intr_mode_unbusy' to 'sdla_t'
* Oct 18, 1997 Jaspreet Singh Added structure to maintain global driver
* statistics.
* Jan 15, 1997 Gene Kozin Version 3.1.0
* o added UDP management stuff
