2011-01-16vmxnet3: Add locking for access to command registerShreyas Bhatewara1-0/+1
Access to cmd register is racey, especially in smp environments. Protect it using a spinlock. Signed-off-by: Matthieu Bucchianeri <matthieu@vmware.com> Signed-off-by: Shreyas N Bhatewara <sbhatewara@vmware.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2010-11-20net-next: Add multiqueue support to vmxnet3 driverShreyas Bhatewara1-22/+51
Add multiqueue support to vmxnet3 driver This change adds multiqueue and thus receive side scaling support to vmxnet3 device driver. Number of rx queues is limited to 1 in cases where MSI is not configured or one MSIx vector is not available per rx queue Signed-off-by: Shreyas Bhatewara <sbhatewara@vmware.com> Reviewed-by: Bhavesh Davda <bhavesh@vmware.com> Signed-off-by: David S.

2010-10-25vmxnet3: remove set_flag_le{16,64} helpersHarvey Harrison1-15/+0
It's easier to just annotate the constants as little endian types and set/clear the flags directly. Signed-off-by: Harvey Harrison <harvey.harrison@gmail.com> Signed-off-by: Shreyas Bhatewara <sbhatewara@vmware.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2010-10-21vmxnet3: make bit twiddle routines inlinestephen hemminger1-3/+14
Gcc doesn't usually handle inline across compilation units, and the functions don't have to be global in scope. Move the set/reset flag functions int the existing vmxnet3 header.

2010-07-26net-next: Fix an overflow bug in vmxnet3 Tx descriptorBhavesh Davda1-2/+2
Fix an overflow bug in vmxnet3 Tx descriptor This patch fixes a bug where a 16K buffer on a Tx descriptor was overflowing into the 'gen' bit in the descriptor thereby corrupting the descriptor and stalling the transmit ring.

2010-07-20net-next: vmxnet3 fixes [5/5] Respect the interrupt type in VM configurationShreyas Bhatewara1-2/+2
Respect the interrupt type set in VM configuration. When interrupt type is not auto, do not ignore the interrupt type set from VM configuration. Signed-off-by: Shreyas Bhatewara <sbhatewara@vmware.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2009-11-17net: Getting rid of the x86 dependency to built vmxnet3Shreyas Bhatewara1-4/+8
This patch removes config dependency on x86 to build vmxnet3 driver. Thus the driver can be built on big endian architectures now. Although vmxnet3 is not supported on VMs other than x86 architecture, all this code goes in to ensure correctness. If the code is not dependent on x86, it should not assume little endian architecture in any of its operations. Signed-off-by: Shreyas Bhatewara <sbhatewara@vmware.com> Signed-off-by: David S.

2009-10-17vmxnet3: use dev_dbg, fix build for CONFIG_BLOCK=nRandy Dunlap1-1/+1
vmxnet3 was using dprintk() for debugging output. This was defined in <linux/dst.h> and was the only thing that was used from that header file. This caused compile errors when CONFIG_BLOCK was not enabled due to bio* and BIO* uses in the header file, so change this driver to use dev_dbg() for debugging output. include/linux/dst.h:520: error: dereferencing pointer to incomplete type include/linux/dst.h:520: error: 'BIO_POOL_BITS' undeclared (first use in this function) include/linux/dst.h:521: error: dereferencing pointer to incomplete type include/linux/dst.h:522: error: dereferencing pointer to incomplete type include/linux/dst.h:525: error: dereferencing pointer to incomplete type make[4]: *** [drivers/net/vmxnet3/vmxnet3_drv.o] Error 1 Signed-off-by: Randy Dunlap <randy.dunlap@oracle.com> Signed-off-by: Bhavesh Davda <bhavesh@vmware.com> Signed-off-by: David S.
