Lite5200 full duplex support

I'm using Sylvain's
bk tree on a lite5200 evb.  I noticed that the FEC driver is hard
coded to only support half duplex 10/100 auto-negotiation.  Is that
intentional?  Are there any known problems with running full duplex?

I modified the code to allow full duplex and I haven't observed any
problems yet.  (w/ nfsroot and compiling apps on the target natively)


BTW, here's what I changed:
drivers/net/fec_mpc52xx/fec_phy.c line 294 (phy_info_lxt971)
        { mk_mii_write(MII_REG_ANAR, 0x0A1), NULL }, /* 10/100, HD */
        { mk_mii_write(MII_REG_ANAR, 0x1E1), NULL }, /* 10/100, HD */
