Subject: [PATCH] net: ethernet: micrel: ksz884x.c: Remove some unused functions
Removes some functions that are not used anywhere:
hw_w_phy_link_md() hw_r_phy_link_md() hw_w_phy_polarity()
hw_r_phy_polarity() hw_w_phy_crossover() hw_r_phy_crossover()
hw_r_phy_rem_cap() hw_w_phy_auto_neg() hw_r_phy_auto_neg()
hw_r_phy_link_stat() sw_get_addr() port_chk_prio() port_chk_replace_vid()
port_chk_802_1p() port_chk_diffserv() sw_chk_unk_def_port()
sw_cfg_unk_def_port() sw_cfg_chk_unk_def_deliver() sw_cfg_unk_def_deliver()
port_chk_in_filter() port_chk_dis_non_vid() port_cfg_in_filter()
port_cfg_dis_non_vid() port_chk_rmv_tag() port_chk_ins_tag()
port_cfg_rmv_tag() port_cfg_ins_tag() sw_flush_dyn_mac_table() port_cfg_tx()
port_cfg_rx() port_chk_force_flow_ctrl() port_chk_back_pressure()
port_cfg_force_flow_ctrl() port_chk_broad_storm() hw_ena_intr_bit()
This was partially found by using a static code analysis program called cppcheck.
