Hello,

Why a newer driver (http://www.marvell.com/drivers/upload/install-8_28.tar.bz2,
it's v8.28.1.3, while kernel has v6.23) is not integrated into kernel?
Because of no one submitted it or does it have some problems?
Because w/o it some newer cards are not recognized
(Marvell Technology Group Ltd. 88E8050 Gigabit Ethernet Controller (rev 17)
for example).

Regards,
Nerijus

It was submitted, but has several problems:
  * wasn't done as small pieces; too much whole sale replacement
  * ignored all the bugfixes and work that went into the mainline kernel
  * merges support for two kinds of hardware in one driver

Also, it increases the amount of vendor ugly code; the sk98lin driver
would probably not be accepted today.

While developing the skge and sky2 driver I discovered more problems and
those got fixed in the mainline sk98lin driver. The vendor version has
issues like:
  * does NAPI but has interrupts disabled
  * has a watchdog routine to mask off all the bugs they never managed
    to fix.
  * sets PCI-express parameters to benchmark values that cause
    random hangs and data corruption

That is why I wouldn't recommend the vendor version for any production
systems.

What is a difference between them? Which one supports Marvell Technology
Group Ltd. 88E8050 Gigabit Ethernet Controller (rev 17)?
skge in 2.6.14 does not support it.

sky2 is for 88e8050 and related chips
