net: qed: fix left elements count calculation

2020-06-30T19:38:42Z

[ Upstream commit 97dd1abd026ae4e6a82fa68645928404ad483409 ] qed_chain_get_element_left{,_u32} returned 0 when the difference between producer and consumer page count was equal to the total page count. Fix this by conditional expanding of producer value (vs unconditional). This allowed to eliminate normalizaton against total page count, which was the cause of this bug. Misc: replace open-coded constants with common defines.

qed*: Reduce the memory footprint for Rx path

2016-10-22T21:08:07Z

With the current default values for Rx path i.e., 8 queues of 8Kb entries each with 4Kb size, interface will consume 256Mb for Rx. The default values causing the driver probe to fail when the system memory is low. Based on the perforamnce results, rx-ring count value of 1Kb gives the comparable performance with Rx coalesce timeout of 12 seconds. Updating the default values.

qed*: Fix Kconfig dependencies with INFINIBAND_QEDR

2016-10-14T15:07:22Z

The qedr driver would require a tristate Kconfig option [to allow it to compile as a module], and toward that end we've added the INFINIBAND_QEDR option. But as we've made the compilation of the qed/qede infrastructure required for RoCE dependent on the option we'd be facing linking difficulties in case that QED=y or QEDE=y, and INFINIBAND_QEDR=m. To resolve this, we seperate between the INFINIBAND_QEDR option and the infrastructure support in qed/qede by introducing a new QED_RDMA option which would be selected by INFINIBAND_QEDR but would be a boolean instead of a tristate; Following that, the qed/qede is fixed based on this new option so that all config combinations would be supported.

Add the RoCE-specific LL2 logic [as well as GSI support] over the 'generic' LL2 interface. Signed-off-by: Ram Amrani Signed-off-by: Yuval Mintz Signed-off-by: David S. Miller

qed: Add support for memory registeration verbs

2016-10-04T03:22:47Z

Add slowpath configuration support for user, dma and memory regions registration. Signed-off-by: Ram Amrani Signed-off-by: Yuval Mintz Signed-off-by: David S. Miller

qed: Add support for QP verbs

2016-10-04T03:22:47Z

Add support for the slowpath configurations of Queue Pair verbs which adds, deletes, modifies and queries Queue Pairs. Signed-off-by: Ram Amrani Signed-off-by: Yuval Mintz Signed-off-by: David S. Miller

qed: PD,PKEY and CQ verb support

Add support for the configurations of the protection domain and completion queues. Signed-off-by: Ram Amrani Signed-off-by: Yuval Mintz Signed-off-by: David S. Miller

qed: Add support for RoCE hw init

2016-10-04T03:22:46Z

This adds the backbone required for the various HW initalizations which are necessary for the qedr driver - FW notification, resource initializations, etc. Signed-off-by: Ram Amrani Signed-off-by: Yuval Mintz Signed-off-by: David S. Miller

qede: Add qedr framework

2016-10-04T03:22:46Z

Adds a skeletal implementation of the qede RoCE driver - The qedr has some dependencies of the state of the underlying base interface. This adds some logic required with mutual registrations and the ability to pass updates on 'intresting' events. Signed-off-by: Ram Amrani Signed-off-by: Yuval Mintz Signed-off-by: David S. Miller

qed: Add Light L2 support

2016-10-04T03:22:46Z

Other protocols beside the networking driver need the ability of passing some L2 traffic, usually [although not limited] for the purpose of some management traffic. Signed-off-by: Yuval Mintz Signed-off-by: Ram Amrani Signed-off-by: David S. Miller
