e1000: Fix PCI enable to honor the need_ioport flag

2009-02-12T17:50:28+00:00

commit 4d7155b932b8129c72e2f2714890e20b2a05e0b7 upstream. On machine were no IO ports are assigned the call to pci_enable_device() will fail, even if need_ioport is false, we need to use pci_enable_device_mem() here.

e1000: fix bug with shared interrupt during reset

2009-02-12T17:50:27+00:00

commit 15b2bee22a0390d951301b53e83df88d0350c499 upstream. A nasty bug was found where an MTU change (or anything else that caused a reset) could race with the interrupt code. The interrupt code was entered by a shared interrupt during the MTU change. This change prevents the interrupt code from running while the driver is in the middle of its reset path.

e1000: Use device_set_wakeup_enable

2008-11-16T09:35:56+00:00

Since dev->power.should_wakeup bit is used by the PCI core to decide whether the device should wake up the system from sleep states, set/unset this bit whenever WOL is enabled/disabled using e1000_set_wol(). Accordingly, use device_can_wakeup() for checking if wake-up is supported by the device. Signed-off-by: "Rafael J. Wysocki" Signed-off-by: Jeff Kirsher Signed-off-by: David S. Miller

e1000: allow VLAN devices to use TSO and CSUM offload

2008-10-11T19:25:59+00:00

This patch changes e1000 to set vlan_features so TSO and CSUM offload can be used by VLAN devices, similar as with the other Intel drivers. Signed-off-by: Patrick McHardy Signed-off-by: Jesse Brandeburg Signed-off-by: Jeff Kirsher Signed-off-by: David S. Miller

e1000: don't generate bad checksums for tcp packets with 0 csum

2008-10-09T21:29:26+00:00

When offloading transmit checksums only, the driver was not correctly configuring the hardware to handle the case of a zero checksum. For UDP the correct behavior is to leave it alone, but for tcp the checksum must be changed from 0x0000 to 0xFFFF. The hardware takes care of this case but only if it is told the packet is tcp. same patch as e1000e Signed-off-by: Dave Graham Signed-off-by: Jesse Brandeburg Signed-off-by: Jeff Kirsher Signed-off-by: David S.

e1000: remove unused Kconfig option for disabling packet split

2008-09-25T02:17:42+00:00

Since the e1000/e1000e split, no hardware supported by e1000 supports packet split, just remove the Kconfig option and associated code from the driver. Signed-off-by: Jesse Brandeburg Signed-off-by: Jeff Garzik

e1000: prevent corruption of EEPROM/NVM

2008-09-19T01:40:24+00:00

Andrey reports e1000 corruption, and that a patch in vmware's ESX fixed it. The EEPROM corruption is triggered by concurrent access of the EEPROM read/write. Putting a lock around it solve the problem.

e1000: fix stack size

2008-08-27T20:56:27+00:00

Here's the patch. It shrinks the stack from 1152 bytes to 192 bytes (the first version, that only did the e1000_option part, got it down to 600 bytes). About half comes from not using multiple "e1000_option" structures, the other half comes from turning the "e1000_opt_list[]" arrays into "static const" instead, so that gcc doesn't copy them onto the stack.

e1000: make ioport free

2008-07-22T23:39:14+00:00

This patch makes e1000 driver ioport-free. This corrects behavior in probe function so as not to request ioport resources as long as they are not really needed. This is based on the ioport-free patch of e1000 driver from Auke Kok and Tomohiro Kusumi.
