Author: jfv Date: Wed Nov 26 23:57:23 2008 New Revision: 185353 URL: http://svn.freebsd.org/changeset/base/185353 Log: This delta is primarily a fix for es2lan devices that will sometimes fail to initialize problem due to a lock contention with management hardware. However, in order to deliver that fix it was necessary to take a shared code update as a whole, and this required scattered changes in the core code to be compatible. The em driver now has VLAN HW support added as the igb driver had previously. MFC after: ASAP - in time for 7.1 RELEASE Modified: head/sys/dev/e1000/e1000_80003es2lan.c head/sys/dev/e1000/e1000_82540.c head/sys/dev/e1000/e1000_82541.c head/sys/dev/e1000/e1000_82542.c head/sys/dev/e1000/e1000_82543.c head/sys/dev/e1000/e1000_82571.c head/sys/dev/e1000/e1000_82575.c head/sys/dev/e1000/e1000_82575.h head/sys/dev/e1000/e1000_api.c head/sys/dev/e1000/e1000_api.h head/sys/dev/e1000/e1000_defines.h head/sys/dev/e1000/e1000_hw.h head/sys/dev/e1000/e1000_ich8lan.c head/sys/dev/e1000/e1000_ich8lan.h head/sys/dev/e1000/e1000_mac.c head/sys/dev/e1000/e1000_mac.h head/sys/dev/e1000/e1000_manage.c head/sys/dev/e1000/e1000_nvm.c head/sys/dev/e1000/e1000_osdep.c head/sys/dev/e1000/e1000_osdep.h head/sys/dev/e1000/e1000_phy.c head/sys/dev/e1000/e1000_phy.h head/sys/dev/e1000/e1000_regs.h head/sys/dev/e1000/if_em.c head/sys/dev/e1000/if_em.h head/sys/dev/e1000/if_igb.c Modified: head/sys/dev/e1000/e1000_80003es2lan.c ============================================================================== --- head/sys/dev/e1000/e1000_80003es2lan.c Wed Nov 26 23:41:18 2008 (r185352) +++ head/sys/dev/e1000/e1000_80003es2lan.c Wed Nov 26 23:57:23 2008 (r185353) @@ -32,7 +32,9 @@ ******************************************************************************/ /*$FreeBSD$*/ -/* e1000_80003es2lan +/* + * 80003ES2LAN Gigabit Ethernet Controller (Copper) + * 80003ES2LAN Gigabit Ethernet Controller (Serdes) */ #include "e1000_api.h" @@ -41,7 +43,9 @@ static s32 e1000_init_phy_params_80003e static s32 e1000_init_nvm_params_80003es2lan(struct e1000_hw *hw);
