Subject: [PATCH net-next 03/15] net: phylink: pass neg_mode into
phylink_mii_c22_pcs_config()
Convert fman_dtsec, xilinx_axienet and pcs-lynx to pass the neg_mode
into phylink_mii_c22_pcs_config(). Where appropriate, drivers are
updated to have neg_mode passed into their pcs_config() and
pcs_link_up() functions. For other drivers, we just hoist the call
to phylink_pcs_neg_mode() to their pcs_config() method out of
phylink_mii_c22_pcs_config().
