* cxgbe(4): Various link/media related improvements.Navdeep Parhar2017-07-172-124/+145
| | | | | | | | | | | | | | | | | | | | | | | | - Deal with changes to port_type, and not just port_mod when a transceiver is changed. This fixes hot swapping of transceivers of different types (QSFP+ or QSA or QSFP28 in a QSFP28 port, SFP+ or SFP28 in a SFP28 port, etc.). - Always refresh media information for ifconfig if the port is down. The firmware does not generate tranceiver-change interrupts unless at least one VI is enabled on the physical port. Before this change ifconfig diplayed potentially stale information for ports that were administratively down. - Always recalculate and reapply L1 config on a transceiver change. - Display PAUSE settings in ifconfig. The driver sysctls for this continue to work as well. MFC after: 2 weeks Sponsored by: Chelsio Communications Notes: svn path=/head/; revision=321063

* Chelsio T4/T5 VF driver.John Baldwin2016-09-073-2/+407
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The cxgbev/cxlv driver supports Virtual Function devices for Chelsio T4 and T4 adapters. The VF devices share most of their code with the existing PF4 driver (cxgbe/cxl) and as such the VF device driver currently depends on the PF4 driver. Similar to the cxgbe/cxl drivers, the VF driver includes a t4vf/t5vf PCI device driver that attaches to the VF device. It then creates child cxgbev/cxlv devices representing ports assigned to the VF. By default, the PF driver assigns a single port to each VF. t4vf_hw.c contains VF-specific routines from the shared code used to fetch VF-specific parameters from the firmware. t4_vf.c contains the VF-specific PCI device driver and includes its own attach routine. VF devices are required to use a different firmware request when transmitting packets (which in turn requires a different CPL message to encapsulate messages). This alternate firmware request does not permit chaining multiple packets in a single message, so each packet results in a firmware request. In addition, the different CPL message requires more detailed information when enabling hardware checksums, so parse_pkt() on VF devices must examine L2 and L3 headers for all packets (not just TSO packets) for VF devices. Finally, L2 checksums on non-UDP/non-TCP packets do not work reliably (the firmware trashes the IPv4 fragment field), so IPv4 checksums for such packets are calculated in software. Most of the other changes in the non-VF-specific code are to expose various variables and functions private to the PF driver so that they can be used by the VF driver. Note that a limited subset of cxgbetool functions are supported on VF devices including register dumps, scheduler classes, and clearing of statistics. In addition, TOE is not supported on VF devices, only for the PF interfaces.

* Make SGE parameter handling more VF-friendly.John Baldwin2016-08-152-0/+7
| | | | | | | | | | | | | | | | | | | | Add fields to hold the SGE control register and free list buffer sizes to the sge_params structure. Populate these new fields in t4_init_sge_params() for PF devices and change t4_read_chip_settings() to pull these values out of the params structure instead of reading registers directly. This will permit t4_read_chip_settings() to be reused for VF devices which cannot read SGE registers directly. While here, move the call to t4_init_sge_params() to get_params__post_init(). The VF driver will populate the SGE parameters structure via a different method before calling t4_read_chip_settings().
