Subject: [PATCH net] net: stmmac: dwmac4: fix PCS duplex mode decode
dwmac4 was decoding the duplex mode from the GMAC_PHYIF_CONTROL_STATUS
register incorrectly, using GMAC_PHYIF_CTRLSTATUS_LNKMOD_MASK (value 1)
rather than GMAC_PHYIF_CTRLSTATUS_LNKMOD (bit 16). Fix this.
Thanks to Abhishek Chauhan for providing a response on this issue.
