Subject: RE: [RFC: 2.6 patch] drivers/net/igb/: #if 0 unused functions

With the exception of the igb_mta_set function these functions can be
removed.  I will try to work with Jeff Kirsher to have a pair of patches
submitted to clean up the igb_mta_set function for correct use and
remove the extra functions.

Thanks,

Alex

In commit 2d064c06fecadadcb81a452acd373af00dfb1fec
(igb: add 82576 MAC support) the following functions
became added unused resp. lost all of their users:
- e1000_82575.c: igb_translate_register_82576()
- e1000_mac.c: igb_init_rx_addrs()
- e1000_mac.c: igb_mta_set()
- e1000_mac.c: igb_update_mc_addr_list()
