Chien Tung 09124e1913 RDMA/nes: Add support for KR device id 0x0110
Add support for KR device id 0x0110.  While at it, cleanup
nes_init_phy() by splitting it into nes_init_1g_phy() and
nes_init_2025_phy().

Remove support for NES_PHY_TYPE_IRIS, which was used on an XFP board
that was only manufactured in small quantities and given out for evals
in even smaller quantities.

Chien Tung 6336936600 RDMA/nes: Mitigate compatibility issue regarding PCIe write credits
Under heavy load, there is an compatibility issue regarding PCIe write
credits with certain chipsets.  It can be mitigated by limiting read
requests to 256 Bytes.

This workaround is always enabled for Tbird2 on Gladius.  We also add
a module parameter to enable workaround for non-Gladius cards.

Johannes Berg e174961ca1 net: convert print_mac to %pM
This converts pretty much everything to print_mac. There were
a few things that had conflicts which I have just dropped for
now, no harm done.

I've built an allyesconfig with this and looked at the files
that weren't built very carefully, but it's a huge patch.

Faisal Latif 6492cdf3a2 RDMA/nes: CM connection setup/teardown rework
Major rework of CM connection setup/teardown.  We had a number of issues
with MPI applications not starting/terminating properly over time.
With these changes we were able to run longer on larger clusters.

* Remove memory allocation from nes_connect() and nes_cm_connect().
* Fix mini_cm_dec_refcnt_listen() when destroying listener.
* Remove unnecessary code from schedule_nes_timer() and nes_cm_timer_tick().
* Functionalize mini_cm_recv_pkt() and process_packet().
* Clean up cm_node->ref_count usage.
* Reuse skbs if available.

Roland Dreier dd37818dbd RDMA/nes: Fix up nes_lro_max_aggr module parameter
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.  Move everything
   related to the parameter to the file nes_hw.c where it is actually
   used.

otherwise there is a window after tasklet_kill() where a new interrupt
