2011-05-09be2net: Fixed bugs related to PVID.Somnath Kotur
Fixed bug to make sure 'pvid' retrieval will work on big endian hosts. Fixed incorrect comparison between the Rx Completion's 16-bit VLAN TCI and the PVID. Now comparing only the relevant 12 bits corresponding to the VID. Renamed 'vid' field under Rx Completion to 'vlan_tag' to reflect accurate description.

2011-04-21be2net: increment work_counter in be_workerIvan Vecera
The commit 609ff3b ("be2net: add code to display temperature of ASIC") adds support to display temperature of ASIC but there is missing increment of work_counter in be_worker. Because of this 1) the function be_cmd_get_die_temperature is called every 1 second instead of every 32 seconds 2) be_cmd_get_die_temperature is called, although it is not supported. This patch fixes this bug. Signed-off-by: Ivan Vecera <ivecera@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2010-10-21vlan: Don't check for vlan group before vlan_tx_tag_present.Jesse Gross
Many (but not all) drivers check to see whether there is a vlan group configured before using a tag stored in the skb. There's not much point in this check since it just throws away data that should only be present in the expected circumstances. However, it will soon be legal and expected to get a vlan tag when no vlan group is configured, so remove this check from all drivers to avoid dropping the tags.
