The remaining uses of tg3_nvram_read_swab() either intended to read the
data from NVRAM exactly as tg3_nvram_read_be32() did or hide deeper
interpretations of the data. For the former case, a direct replacement
of tg3_nvram_read_swab() with tg3_nvram_read_be32() is in order. For
the latter case, we remove tg3_nvram_read_swab() and document what the
code is really doing.

Any software requesting NVRAM data as it exists on NVRAM is necessarily
requesting that the results be returned as a bytestream. A bytestream
data read in from the device can also be thought to be in big endian
format. Therefore, all the LE notations in the driver are mislabeled.
This patch converts all LE notations to BE notations, carefully
evaluating the surrounding code in the process.

This patch removes the blind byteswap of NVRAM data as it is read in.
To preserve the logic at the call sites, this patch also inverts every
call to tg3_nvram_read() and tg3_nvram_read_swab(). The call swap gets
confusing within tg3_nvram_read_le() (LE is a misnomer), but the reader
should be able to convince himself / herself that the resulting behavior
is still unchanged.

The ethtool interface has acquired some new enumerations since the
tg3 driver's tg3_set_settings() error checking code was written. The
error checking code is no longer complete. This patch rewrites the
error checking so that it is future-proofed.

The hardware's MTU is configured so that it will accept packets whose
VLAN tag is left inline. This means that the hardware will also accept
other packets larger than the desired MTU size. This patch checks for
and discards packets that are larger than the requested MTU but are not
VLAN tagged frames.

Commit 6833c043f9fc03696fde623914c4a0277df2a0bc introduced the phy
auto-powerdown capability. While the APD feature only works for 5761
and 5784 asic revisions, the (harmless portion of the) code was applied
to all 5705 and newer devices. However, the 5906 phy departs from the
usual design. This commit was interfering with the 5906's ability to
negotiate link against some switches. This patch corrects the problem.

[ 2845.743742] Rebooting in 3 seconds..
My logitec bluetooth mouse trying connect to pc, but
pc side reject the connection again and again. then panic happens.
The reason is due to hci_conn_del_sysfs now called in hci_event_packet,
the del work is done in a workqueue, so it's possible done before
skb_queue_purge called.
I move the hci_conn_del_sysfs after skb_queue_purge just as that before
marcel's commit.
Remove the hci_conn_del_sysfs in hci_conn_hash_flush as well due to
hci_conn_del will deal with the work.

Userspace pairing code can be simplified if it doesn't have to fall
back to using L2CAP_LM in the case of L2CAP raw sockets. This patch
allows the BT_SECURITY socket option to be used for these sockets.

The CID value of L2CAP sockets need to be set to zero. All userspace
applications do this via memset() on the sockaddr_l2 structure. The
RFCOMM implementation uses in-kernel L2CAP sockets and so it has to
make sure that l2_cid is set to zero.
