ganesanr@broadcom.com - Jan. 29, 2013, 9:11 a.m.
From: Ganesan Ramalingam <ganesanr@broadcom.com>

Add support for the Network Accelerator Engine on Netlogic XLR/XLS
MIPS SoCs. The XLR/XLS NAE blocks can be configured as one 10G
interface or four 1G interfaces. This driver supports blocks
with 1G ports.

 This patch has to be merged through netdev tree.
 Please review and let me know if there are any comments or suggestions.

Why add a netlogic directory when the company is now a part of Broadcom?

Either implement them or don't.  I'm guessing that phylib can handle
get_settings and set_settings for you.

If nlm_fmn_send() fails then you need to free the skbuff.

32-bit byte counters for a 1G/10G device?  Seriously?

You should probably be implementing ndo_get_stats64 to provide 64-bit
stats even on a 32-bit kernel.

A watchdog timeout of 1000 seconds is ridiculous.  I guess someone just
kept seeing the watchdog fire and increasing the timeout, and never
thought about *why* this was happening.

Ben, Thank you for your comments, will submit the driver with fixes.
Reply inline.

All our submissions are still following the Netlogic convention, look at
arch/mips/netlogic/, this will be changed in future with BRCM wrapper.

Yes, all are 32-bit byte counters
