Fixed issues

We've updated these drivers to support the latest devices and to address some minor problems. (Ref# 41574)

This patch includes the following new drivers:

• devn-micrel8841.so — supports the Micrel 8841 (1 port) or 8842 (2 port) Ethernet controller.
• devn-rtl8169 — supports the Realtek 8169 Gigabit Ethernet controller.

The devn-i82544.so driver supports the following Intel i82544 chipsets:

The devn-speedo.so driver supports the following Intel chipsets:

This patch also addresses the following issues:

devn-crys8900.so

This driver no longer drops received packets. (Ref# 28876)

devn-el900.so

• This driver now supports CardBus cards on big-endian machines.
• We fixed some issues with big-endianness.
• This driver now supports the IXP200 Southbridge 905 chip.
• We corrected the initialization of the io-net endpoint.
• Packets are now queued directly to the tx descriptors.
• We cleaned up the receive logic.
• We fixed a memory leak in the transmit routine.
• The devn-el900.so driver now displays the negotiated duplex in the output from nicinfo (Ref# 17145)
• The driver now correctly negotiates the duplex setting when given just the speed on the command line. (Ref# 17155)
• The driver now works correctly for Version A cards. (Ref# 18263)
• We fixed the npkt flags for io-net. (Ref# 19092)
• The driver no longer leaks transmission packets. (Ref# 19226)
• If you disconnect the cable and later reconnect it, the driver now reports the correct speed and duplex settings. (Ref# 20417)
• The driver no longer loses received packets on SystemH boards. (Ref# 21092)
• Only root can now change the multicast settings. (Ref# 26539)
• We've added a probe_phy option that lets you control periodic PHY probing with respect to packet loss under load. (Ref# 28651)
• This driver now negotiates links with a 3C556 device. (Ref# 38067)

devn-epic.so

• The fiber connector now works correctly.
• We added range checking of multicast addresses.
• We've added a TX_FLUSH devctl() command to support the Liteweight L4 version of Qnet.
• We fixed the npkt flags for io-net.
• We corrected the promiscuous and multicast counts.
• We added a probe_phy option for 3-second periodic packet loss.
• We corrected the initialization of the io-net endpoint.
• The driver now properly handles invalid multicast addresses (Ref# 15736)
• The devn-epic.so driver now displays the negotiated duplex in the output from nicinfo (Ref# 17153)
• The multicast filter is now empty by default. (Ref# 20416)
• Transmission no longer locks up in a stress test. (Ref# 24099)

devn-speedo.so

• We've added a TX_FLUSH devctl() command to support the Liteweight L4 version of Qnet.
• We corrected the initialization of the io-net endpoint.
• If you specify the verbose option, the driver logs transmission errors to sloginfo.
• This driver no longer delays for 10 milliseconds when io-net sends it a devctl() command. (Ref# 23331; Ticket ID 68013)
• We've added a probe_phy option that lets you control periodic PHY probing with respect to packet loss under load. (Ref# 28648)

devn-tulip.so

• We've added a TX_FLUSH devctl() command to support the Liteweight L4 version of Qnet.
• We fixed the npkt flags for io-net.
• Added logic for Macronix link down detection.
• Logic added to check for chip revisions for multicast address ranges.
• We corrected the initialization of the io-net endpoint.
• The internal packet queue no longer overflows when packets are sent very quickly to the driver. (Ref# 23962)
• We've added a probe_phy option that lets you control periodic PHY probing with respect to packet loss under load. (Ref# 28643)

Known issues

devn-crys8900.so

This driver can't join a multicast group unless promiscuous mode is turned on. (Ref# 15993)

devn-el900.so

This driver can lock up under a heavy packet load. (Ref# 16055)
