ChangeSet 1.1595.7.20, 2003/07/30 13:47:44-07:00, [EMAIL PROTECTED]
[PATCH] USB: AX8817x mii/ethtool fixes among others
This patch:
Adds the Intellinet device IDs
Adds msg_level support (to be utilized in the future)
Fixes ethtool/mii support so link checking actually works
Changed timeout on usb_fill_int_urb to support High Speed ([EMAIL PROTECTED])
Added devdbg/err/info defines borrowed from usbnet
Changed strlcpy to strncpy
Key issue not currently resolved (as brought up by [EMAIL PROTECTED]) is
that the receive performance is terrible on OHCI. I ran a set of tests
with ttcp and transmit performance achieved 6146.16 KB/sec but receive
only yielded 466.26 KB/sec which really sucks (sorry for the technical
jargon). In porting the driver to 2.5 I had to pull the transmit
queueing that Tivo had originally used for the driver to even function.
My initial attempts at pulling the receive queueing met with many
Ooopses thus I backed off. Looks like I will need to dig in again on
that one.
