      RDMA/iwcm: Get rid of enum iw_cm_event_status · d0c49bf3
      由 Roland Dreier 提交于 
      The IW_CM_EVENT_STATUS_xxx values were used in only a couple of places;
cma.c uses -Exxx values instead, and so do the amso1100, cxgb3 and cxgb4
drivers -- only nes was using the enum values (with the mild consequence
that all nes connection failures were treated as generic errors rather
than reported as timeouts or rejections).

We can fix this confusion by getting rid of enum iw_cm_event_status and
using a plain int for struct iw_cm_event.status, and converting nes to
use -Exxx as the other iWARP drivers do.

This also gets rid of the warning

      ethtool: cosmetic: Use ethtool ethtool_cmd_speed API · 70739497
      由 David Decotigny 提交于 
      This updates the network drivers so that they don't access the
ethtool_cmd::speed field directly, but use ethtool_cmd_speed()
instead.

For most of the drivers, these changes are purely cosmetic and don't
fix any problem, such as for those 1GbE/10GbE drivers that indirectly
call their own ethtool get_settings()/mii_ethtool_gset(). The changes
are meant to enforce code consistency and provide robustness with
future larger throughputs, at the expense of a few CPU cycles for each
ethtool operation.

All drivers compiled with make allyesconfig ion x86_64 have been
updated.

Tested: make allyesconfig on x86_64 + e1000e/bnx2x work

      net: percpu net_device refcount · 29b4433d
      由 Eric Dumazet 提交于 
      We tried very hard to remove all possible dev_hold()/dev_put() pairs in
network stack, using RCU conversions.

There is still an unavoidable device refcount change for every dst we
create/destroy, and this can slow down some workloads (routers or some
app servers, mmap af_packet)

We can switch to a percpu refcount implementation, now dynamic per_cpu
infrastructure is mature. On a 64 cpus machine, this consumes 256 bytes
per device.

On x86, dev_hold(dev) code :

before
        lock    incl 0x280(%ebx)
after:
        movl    0x260(%ebx),%eax
        incl    fs:(%eax)

by printing u64 quantities by casting to unsigned long and long and
