We have a system with a P1022 connected to a 5461S in SGMII mode.

In order to make it work in SGMII mode, I set TBI ANA to 0x4001 as per
AN3869. Note that those bit are described as reserved in the P1022 doc 
that I have.
I was then able to transfer data at 100/1000 (10 not tested).

As per AN3869 a value of 0x1a0 is  for 1000BASE-X.


Looking at the tsec driver (drivers/net/tsec.c), one can see:

#define TBIANA_SETTINGS ( \
         TBIANA_ASYMMETRIC_PAUSE \
         | TBIANA_SYMMETRIC_PAUSE \
         | TBIANA_FULL_DUPLEX \
         )
==> 0x1a0

if (regs->ecntrl & ECNTRL_SGMII_MODE)
         tsec_configure_serdes(priv);

That would mean the TBI ANA is not set correctly when SGMII
is reported.

Please can you verify this.

Cheers.
