      mac80211: convert HW flags to unsigned long bitmap · 30686bf7
      由 Johannes Berg 提交于 
      As we're running out of hardware capability flags pretty quickly,
convert them to use the regular test_bit() style unsigned long
bitmaps.

This introduces a number of helper functions/macros to set and to
test the bits, along with new debugfs code.

The occurrences of an explicit __clear_bit() are intentional, the
drivers were never supposed to change their supported bits on the
fly. We should investigate changing this to be a per-frame flag.

      mac80211: remove support for IFF_PROMISC · df140465
      由 Johannes Berg 提交于 
      This support is essentially useless as typically networks are encrypted,
frames will be filtered by hardware, and rate scaling will be done with
the intended recipient in mind. For real monitoring of the network, the
monitor mode support should be used instead.

Removing it removes a lot of corner cases.

      staging: vt6656: replace memcpy by ether_addr_copy · c5f9e99b
      由 Aya Mahfouz 提交于 
      This patch fixes the following checkpatch.pl warning:

Prefer ether_addr_copy() over memcpy() if the Ethernet addresses are
__aligned(2)

The changes were applied using the following coccinelle
rule:
@@ expression e1, e2; @@
- memcpy(e1, e2, ETH_ALEN);
+ ether_addr_copy(e1, e2);

All variables defined in vnt_mac_set_key start at even offsets
making the variables aligned to the u16 datatype.

      This patch focuses on fixing the following warning generated
by checkpatch.pl for the file rxtx.c

Prefer ether_addr_copy() over memcpy() if the Ethernet addresses
are __aligned(2)

@@ expression e1, e2; @@

According to ether_addr_copy() description and functionality,
all Ethernet addresses should align to the u16 datatype.
