Always-Installed Network Drivers
The following sections describe network drivers and devices that are automatically
installed.
100Base-T
The btlan driver supports 100BASE-T Ethernet adapters, like the PCI 100BASE-T
single-port card A5230A and the 4-port PCI 100BASE-T cards A5506A/A5506B.
Summary of Change
The changes to the 100BASE-T driver, btlan, in the HP-UX 11i v2 release are to provide
support for interrupt migration and OLAR on Itanium-based platforms.
Impact
Interrupt migration provides the capability for the user to move device interrupts
amongst processors allowing the balancing of the system's interrupt load, thereby
improving performance.
The OLAR feature enables the addition and/or replacement of 100Base-T adapter cards
without shutting down the system. For more information, see On-line Addition and
Replacement (OLAR) of I/O Adapters (see page 45).
Compatibility
There are no compatibility issues.
Performance
There are no performance issues.

1000Base-T (Gigabit Ethernet)
The Gigabit Ethernet LAN adapters are data link adapters that support the IEEE
802.3z standard for 1000Base-SX operation over fiber and the IEEE 802.3ab standard
for 1000Base-T operation over 4-pair CAT-5 copper wiring.
