* cxgb4/cxgb4vf: Fixes regression in perf when tx vlan offload is disabledHariprasad Shenai2016-07-311-1/+1
| | | | | | | | | | | | | | | | | The commit 637d3e997351 ("cxgb4: Discard the packet if the length is greater than mtu") introduced a regression in the VLAN interface performance when Tx VLAN offload is disabled. Check if skb is tagged, regardless of whether it is hardware accelerated or not. Presently we were checking only for hardware acclereated one, which caused performance to drop to ~0.17Mbps on a 10GbE adapter for VLAN interface, when tx vlan offload is turned off using ethtool. The ethernet head length calculation was going wrong in this case, and driver ended up dropping packets.

* cxgb4/cxgb4vf: For T6 adapter, set FBMIN to 64 bytesHariprasad Shenai2016-03-021-1/+12
| | | | | | | | | | | | T4 and T5 hardware will not coalesce Free List PCI-E Fetch Requests if the Host Driver provides more Free List Pointers than the Fetch Burst Minimum value. So if we set FBMIN to 64 bytes and the Host Driver supplies 128 bytes of Free List Pointer data, the hardware will issue two 64-byte PCI-E Fetch Requests rather than a single coallesced 128-byte Fetch Request. T6 fixes this. So, for T4/T5 we set the FBMIN value to 128 Signed-off-by: Hariprasad Shenai <hariprasad@chelsio.com> Signed-off-by: David S. Miller <davem@davemloft.net>

* cxgb4/cxgb4vf: function and argument name cleanupHariprasad Shenai2015-05-271-2/+2
| | | | | | | | | | | | | | | | | | This patch changes variable name 'fn' to 'pf' of structure adapter. A 'fn' usually stands for PCI function which could be a PF or a VF. However, the use of this particular variable is explicitly limited to PF only. So, be specific about it in the variable name. Also corrects arguments passed for fn t4_ofld_eq_free, t4_ctrl_eq_free, t4_eth_eq_free, t4_iq_free, t4_alloc_vi, t4_fw_hello, t4_wr_mbox and t4_cfg_pfvf function. Also renames cxgb4_t4_bar2_sge_qregs to t4_bar2_sge_qregs and renames the latter function name in cxgb4vf driver to t4vf_bar2_sge_qregs to avoid conflicts. Also fixes alignment for these function.

* cxgb4/cxgb4vf: Code cleanup to enable T4 Configuration File supportVipul Pandya2012-09-271-2/+3
| | | | | | | | | | | | | | | | This patch adds new enums and macros to enable T4 configuration file support. It also removes duplicate macro definitions. It fixes the build failure in cxgb4vf driver introduced because of old macro definition removal. It also performs SGE initialization based on T4 configuration file is provided or not. If it is provided then it uses the parameters provided in it otherwise it uses hard coded values.

* netvm: propagate page->pfmemalloc from skb_alloc_page to skbMel Gorman2012-08-011-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The skb->pfmemalloc flag gets set to true iff during the slab allocation of data in __alloc_skb that the the PFMEMALLOC reserves were used. If page splitting is used, it is possible that pages will be allocated from the PFMEMALLOC reserve without propagating this information to the skb. This patch propagates page->pfmemalloc from pages allocated for fragments to the skb. It works by reintroducing and expanding the skb_alloc_page() API to take an skb. If the page was allocated from pfmemalloc reserves, it is automatically copied. If the driver allocates the page before the skb, it should call skb_propagate_pfmemalloc() after the skb is allocated to ensure the flag is copied properly. Failure to do so is not critical. The resulting driver may perform slower if it is used for swap-over-NBD or swap-over-NFS but it should not result in failure.

* ethernet: Remove casts to same typeJoe Perches2012-06-061-3/+2Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Adding casts of objects to the same type is unnecessary and confusing for a human reader. For example, this cast: int y; int *p = (int *)&y; I used the coccinelle script below to find and remove these unnecessary casts. I manually removed the conversions this script produces of casts with __force, __iomem and __user. @@ type T; T *p; @@ - (T *)p + p A function in atl1e_main.c was passed a const pointer when it actually modified elements of the structure. Change the argument to a non-const pointer. A function in stmmac needed a __force to avoid a sparse warning. Added it. Signed-off-by: Joe Perches <joe@perches.com> Signed-off-by: David S.

(Some drivers used a mix of these interfaces and alloc_pages()) When allocating a page given to device for DMA transfer (device to memory), it makes sense to use a cold one (__GFP_COLD) Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> CC: Jeff Kirsher <jeffrey.t.kirsher@intel.com> CC: Dimitris Michailidis <dm@chelsio.com> Signed-off-by: David S.
