In ME systems, the ME handles this on exit from + Sx(Sticky mode) state. In non-ME, the driver handles it. Add a check + for non-ME system to the driver code that handles that. + +* **e1000/base: Increase timeout of reset check.** + + Previously, in check_reset_block RSPCIPHY was polled for 100 ms before + determining that the ME veto is set. It's not enough. It need to be increased + to 300 ms. + +* **e1000/base: Disable IPv6 extension header parsing on 82575.** + + Disable IPv6 options as per hardware limitation. + +* **e1000/base: Prevent ULP flow if cable connected.** + + Enabling ulp on link down when cable is connect caused an infinite + loop of linkup/down indications in the NDIS driver. + After discussed, correct flow is to enable ULP only when cable is + disconnected. + +* **e1000/base: Support different EEARBC for i210.** + + EEARBC has changed on i210. It means EEARBC has a different address on + i210 than on other NICs. So, add a new entity named EEARBC_I210 to the + register list and make sure the right one is being used on i210. + +* **e1000/base: Fix K1 configuration** + + This patch is for the following updates to the K1 configurations: + Tx idle period for entering K1 should be 128 ns. + Minimum Tx idle period in K1 should be 256 ns. + +* **e1000/base: Fix link detect flow** + + In case that auto-negotiate is not enabled, call + e1000_setup_copper_link_generic instead of e1000_phy_setup_autoneg. + +* **e1000/base: Fix link check for i354 M88E1112 PHY** + + e1000_check_for_link_media_swap() is supposed to check PHY page 0 for + copper and PHY page 1 for "other" (fiber) link. We switched back from + page 1 to page 0 too soon, before e1000_check_for_link_82575() is + executed and we were never finding link on fiber (other). + + If the link is copper, as the M88E1112 page address is set to 1, it should be + set back to 0 before checking this link. + +* **e1000/base: Fix beacon duration for i217** + + Fix for I217 Packet Loss issue - The Management Engine sets the FEXTNVM4 + Beacon Duration incorrectly. This fix ensures that the correct value will + always be set. Correct value for this field is 8 usec. + +* **e1000/base: Fix TIPG for non 10 half duplex mode** + + TIPG value is increased when setting speed to 10 half to prevent + packet loss. However, it was never decreased again when speed + changes. This caused performance issues in the NDIS driver. + Fix this to restore TIPG to default value on non 10 half. + +* **e1000/base: Fix reset of DH89XXCC SGMII** + + For DH89XXCC_SGMII, write flush leaves registers of this device trashed + (0xFFFFFFFF). Add check for this device. + Also, after both for Port SW Reset and Device Reset case, platform should + wait at least 3ms before reading any registers. Since waiting is + conditionally executed only for Device Reset - remove the condition. + +* **e1000/base: Fix redundant PHY power down for i210** + + Bit 11 of PHYREG 0 is used to power down PHY. The use of PHYREG 16 is + unnecessary any more. + +* **e1000/base: fix jumbo frame CRC failures** + + change the value of register 776.20[11:2] for jumbo mode from 0x1A to 0x1F. + This is to enlarge the gap between read and write pointers in the TX Fifo. + And replace the magic number with a macro by the way. + +* **e1000/base: Fix link flap on 82579** + + Several customers have reported a link flap issue on 82579. The symptoms + are random and intermittent link losses when 82579 is connected to specific + switches. Issue has been root caused as interoperability problem between + the NIC and at least some Broadcom PHYs in the Energy Efficient Ethernet + wake mechanism. + To fix the issue, we are disabling the Phase Locked Loop shutdown in 100M + Low Power Idle. This solution will cause an increase of power in 100M EEE + link. It may cost additional 28mW in this specific mode. + Libraries ~~~~~~~~~ -- 1.9.3
