Adrian Bunk 7aa55fcec2 [PATCH] drivers/net/skfp/: cleanups 
This patch contains the following cleanups:
- make needlessly global code static
- remove the completely unused smtparse.c
- remove the following unused global functions:
  - drvfbi.c: init_dma
  - drvfbi.c: dis_dma
  - drvfbi.c: get_rom_byte
  - drvfbi.c: mac_drv_vpd_read
  - drvfbi.c: mac_drv_pci_fix
  - fplustm.c: mac_set_func_addr
  - fplustm.c: mac_del_multicast
  - hwmtm.c: mac_drv_rx_frag
  - pcmplc.c: pcm_set_lct_short
  - smt.c: smt_please_reconnect
  - smt.c: smt_change_t_neg
  - smtdef.c: smt_set_defaults
