Read the Ethernet-HOWTO, 11 available from <http://www.tldp.org/docs.html#howto>. 12 13 If unsure, say Y. 14 15 Note that the answer to this question doesn't directly affect the 16 kernel: saying N will just cause the configurator to skip all 17 the remaining Blackfin card questions. If you say Y, you will be 18 asked for your specific card in the following questions. 19 20if NET_BFIN 21 22config BFIN_MAC 23 tristate "Blackfin on-chip MAC support" 24 depends on (BF516 || BF518 || BF526 || BF527 || BF536 || BF537) 25 select CRC32 26 select MII 27 select PHYLIB 28 select BFIN_MAC_USE_L1 if DMA_UNCACHED_NONE 29 ---help--- 30 This is the driver for Blackfin on-chip mac device.
