2019-06-13rdma: Remove nesJason Gunthorpe1-574/+0
This driver was first merged over 10 years ago and has not seen major activity by the authors in the last 7 years. However, in that time it has been patched 150 times to adapt it to changing kernel APIs. Further, the hardware has several issues, like not supporting 64 bit DMA, that make it rather uninteresting for use with modern systems and RDMA.

The pci-core and net-core logic ensure that parameters provided to nes_probe() and nes_netdev_open() are valid, hence the assert print are not possible.

Note that ipoib has no min_mtu set, and thus, the network core's mtu > 0 check is the only lower bounds here. mptlan: - use net core MTU range checking - remove now redundant mpt_lan_change_mtu fddi: - min_mtu = 21, max_mtu = 4470 - remove now redundant fddi_change_mtu (including export) fjes: - min_mtu = 8192, max_mtu = 65536 - The max_mtu value is actually one over IP_MAX_MTU here, but the idea is to get past the core net MTU range checks so fjes_change_mtu can validate a new MTU against what it supports (see fjes_support_mtu in fjes_hw.c) hsr: - min_mtu = 0 (calls ether_setup, max_mtu is 1500) f_phonet: - min_mtu = 6, max_mtu = 65541 u_ether: - min_mtu = 14, max_mtu = 15412 phonet/pep-gprs: - min_mtu = 576, max_mtu = 65530 - remove redundant gprs_set_mtu CC: netdev@vger.kernel.org CC: linux-rdma@vger.kernel.org CC: Stefan Richter <stefanr@s5r6.in-berlin.de> CC: Faisal Latif <faisal.latif@intel.com> CC: linux-rdma@vger.kernel.org CC: Cliff Whickman <cpw@sgi.com> CC: Robin Holt <robinmholt@gmail.com> CC: Jes Sorensen <jes@trained-monkey.org> CC: Marek Lindner <mareklindner@neomailbox.ch> CC: Simon Wunderlich <sw@simonwunderlich.de> CC: Antonio Quartulli <a@unstable.cc> CC: Sathya Prakash <sathya.prakash@broadcom.com> CC: Chaitra P B <chaitra.basappa@broadcom.com> CC: Suganath Prabu Subramani <suganath-prabu.subramani@broadcom.com> CC: MPT-FusionLinux.pdl@broadcom.com CC: Sebastian Reichel <sre@kernel.org> CC: Felipe Balbi <balbi@kernel.org> CC: Arvid Brodin <arvid.brodin@alten.se> CC: Remi Denis-Courmont <courmisch@gmail.com> Signed-off-by: Jarod Wilson <jarod@redhat.com> Signed-off-by: David S.

Support for Packed and Unaligned (PAU) FPDUs is needed for interoperability between NES and non-NES nodes. When the NES hardware detects a PAU frame, it will pass it to the driver to process the frame. NES driver creates a new frame for each FPDU and forwards it to the hardware to be sent to its associated qp.

2008-07-15RDMA/nes: Encapsulate logic nes_put_cqp_request()Roland Dreier1-0/+4

Wrap this up in functions nes_free_cqp_request() and nes_put_cqp_request() to simplify such code.

2008-05-13RDMA/nes: Fix up nes_lro_max_aggr module parameterRoland Dreier1-1/+0
Fix some bugs with the max_aggr module parameter added with LRO support: - The module parameter value ignored and not actually used to set lro_mgr.max_aggr. - MODULE_PARM_DESC had a typo "_mro_" instead of "_lro_" so it didn't end up describing the actual module parameter. - The nes_lro_max_aggr variable was declared as unsigned, but the module_param line said "int" instead of "uint" for the type. - The default value for the parameter was stuck in the permissions field of module_param, which led to nonsensical permissions for the file under /sys/module/iw_nes/param. - The parameter was used in only one file but defined in another, which led to the variable being global for no good reason.
