2 New and changed features in this release

2.1 New features

The following feature is new with this version of IEther-00:

• Support is added for MSI-X interrupts.

AD221A, AD222A, AD393A and the core LAN card on the HP rx2800 server support MSI-X

interrupts. With IEther-00 B11.31.1109 and later, these cards use MSI-X interrupts instead of

LBI (QXCR1001066061). This feature enables support for potential future products.

2.2 Changed features

The following feature is changed with this version of IEther-00:

• The nwmgr_iether(1m) manpage is updated.

The nwmgr_iether(1m) manpage now includes the newly-introduced ifadmin attribute.

This attribute is introduced with patch PHNE_41971 for nwmgr(1m) (QXCR1001104156).
