vmxnet3: fix checks for dma mapping errors

2015-12-01T20:19:16+00:00

vmxnet3_drv does not check dma_addr with dma_mapping_error()
after mapping dma memory. The patch adds the checks and
tries to handle failures.

drivers/net: get rid of unnecessary initializations in .get_drvinfo()

2015-10-16T07:24:10+00:00

Many drivers initialize uselessly n_priv_flags, n_stats, testinfo_len,
eedump_len & regdump_len fields in their .get_drvinfo() ethtool op.
It's not necessary as these fields is filled in ethtool_get_drvinfo().

v2: removed unused variable
v3: removed another unused variable

vmxnet3: prevent receive getting out of sequence on napi poll

2015-07-09T06:36:11+00:00

vmxnet3's current napi path is built to count every rx descriptor we recieve,
and use that as a count of the napi budget.  That means its possible to return
from a napi poll halfway through recieving a fragmented packet accross multiple
dma descriptors.  If that happens, the next napi poll will start with the
descriptor ring in an improper state (e.g. the first descriptor we look at may
have the end-of-packet bit set), which will cause a BUG halt in the driver.

Fix the issue by only counting whole received packets in the napi poll and
returning that value, rather than the descriptor count.

Tested by the reporter and myself, successfully

vmxnet3: Fix memory leaks in rx path (fwd)

2015-06-23T13:26:00+00:00

If rcd length was zero, the page used for frag was not being released. It
was being replaced with a newly allocated page. This change takes care
of that memory leak.

vmxnet3: Register shutdown handler for device (fwd)

2015-06-23T13:25:59+00:00

Implement a handler for pci shutdown so that the driver has an
opportunity to make sure that device is quiesced before the PCI
switches to legacy IRQs. This way the possibility of
"screaming interrupt" is avoided.
