How about: 02:00.0 Ethernet controller: Marvell Technology Group Ltd. 88E8053 PCI-E Gigabit Ethernet Controller (silicon rev 2, firmware/PCI rev 22) This introduces perhaps something even more useful - we know there are really major issues with (eg) 88E8053 before firmware 2.2; is it worth adding a warning, such as: sky2: firmware earlier than rev 2.2 detected - if you experience transmit timeouts, ask vendor for 88E8053 firmware update There are a lot of bug reports on the web pointing the finger at the sky2 driver, and waiting for a 'fixed' version, but the issue is elsewhere...part of the problem, if there is (almost) no documentation/evidence of this problem posted anywhere.
