Firmware reference counts the MPS TCAM entries by PF and VF, but it does not do it for usage within a PF or VF. This patch adds the support to track MPS TCAM entries within a PF.
v1->v2: Use refcount_t type instead of atomic_t for mps reference count Raju Rangoju (4): cxgb4: Re-work the logic for mps refcounting cxgb4: Add MPS TCAM refcounting for raw mac filters cxgb4: Add MPS TCAM refcounting for cxgb4 change mac cxgb4: Add MPS refcounting for alloc/free mac filters drivers/net/ethernet/chelsio/cxgb4/Makefile | 2 +- drivers/net/ethernet/chelsio/cxgb4/cxgb4.h | 53 ++++- drivers/net/ethernet/chelsio/cxgb4/cxgb4_filter.c | 8 +- drivers/net/ethernet/chelsio/cxgb4/cxgb4_main.c | 40 ++-- drivers/net/ethernet/chelsio/cxgb4/cxgb4_mps.c | 242 ++++++++++++++++++++++ 5 files changed, 313 insertions(+), 32 deletions(-) create mode 100644 drivers/net/ethernet/chelsio/cxgb4/cxgb4_mps.c -- 2.12.0
