[dpdk-dev] [PATCH] net/e1000: add minimum support for Broadcom 54616 PHY

[Lu, Wenzhuo]

Hi Chas,
1, Would you like to use this CLI “lspci -nn | grep Eth” to get the device ID of  the NIC?
2, You mentioned “the doc of the platform”. Is it public? If so, could you tell me the link? Just want to understand more about it.
Thanks.


Best regards
Wenzhuo Lu

I derived that value by observing what the ixgbe finds when loading on my platform.  The docs for the platform say that the attached PHY is a Broadcom 54616.  I couldn't find any documentation on this PHY to determine what this value is (i.e. is it really some sort of ID string for that PHY).    I almost suspect that the ixgbe is reading some registers on the PHY that just happen to contain this value after reset.

Supposedly it's similar to the 54618 but that really doesn't provide much more information.  The bnx2x has a driver for the 54618 and nothing that looks similar to that string.
