* igbvf: fix divide by zeroMitch A Williams2012-06-301-11/+18
| | | | | | | | | | | | | | Using ethtool -C ethX rx-usecs 0 crashes with a divide by zero. Refactor this function to fix this issue and make it more clear what the intent of each conditional is. Add comment regarding using a setting of zero.

* igbvf: refactor Interrupt Throttle Rate codeMitch A Williams2012-02-071-9/+10
| | | | | | | | | | | | | | | | | | The existing ITR code is broken and confusing, with lots of similarly-named variables that do different things. Additionally, after the driver carefully determines the optimal interrupt rate for the adapter, it then ignores it and always writes a fixed, suboptimal value. This patch refactors that code to make variable names more descriptive of what they actually do, and then actually writes the calculated result to the hardware. Preliminary testing shows that netperf TCP_STREAM tests goes from ~918Mbps to ~940Mbps, and TCP_RR goes from ~2k transactions/sec up to > 8k.

| | | | | | | | | | | | number of drivers Per discussion with Ben Hutchings and David Miller, go through and remove assignments of "N/A" to fw_version in various drivers' .get_drvinfo routines. While there clean-up some use of bare constants and such. Signed-off-by: Rick Jones <rick.jones2@hp.com> Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | This round of floor sweeping converts strncpy calls in various .get_drvinfo routines to the preferred strlcpy. It also does a modicum of other cleaning in those routines. Signed-off-by: Rick Jones <rick.jones2@hp.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* igbvf: convert to ndo_fix_featuresMichał Mirosław2011-10-161-57/+0
| | | | | | | | | | | | | Private rx_csum flags are now duplicate of netdev->features & NETIF_F_RXCSUM. Removing this needs deeper surgery. Things noticed: - HW VLAN acceleration probably can be toggled, but it's left as is - the resets on RX csum offload change can probably be avoided - there is A LOT of copy-and-pasted code here Signed-off-by: Michał Mirosław <mirq-linux@rere.qmqm.pl> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com>
