When there is no AC power, NIC may not work after changing mac address.
Please refer to following link.
http://www.spinics.net/lists/netdev/msg356572.html
This issue is caused by runtime power management. When there is no AC
power, if we put NIC down (ifconfig down), the driver will be in runtime
suspend state and hardware will be put into D3 state. During this time,
driver cannot access hardware regisers. So if you set new mac address
during this time, it will not be set to hardware. After resume, NIC will
keep using the old mac address and the network will not work normally.
In this patch I add detecting runtime pm status when setting mac address.
If driver is in runtime suspend state, it will skip setting mac address, keep
the new mac address, and set the new mac address during runtime resume.

If we set or get hardware wol setting in runtime suspend state, because
NIC will in D3 state, the hardware registers read by driver will return all

then prints the warning message "rtl_counters_cond == 1 (loop: 1000,

The L3 error will be generated and system will crash during unloading

This happens because CPSW can be power off by PM runtime now when ethX

Hence, ensure that CPSW powered up by PM runtime before performing any

of PM runtime error just leave cpsw_remove() as we can't do anything

The commit 637d3e9973 ("cxgb4: Discard the packet if the length is
greater than mtu") introduced a regression in the VLAN interface
performance when Tx VLAN offload is disabled.
Check if skb is tagged, regardless of whether it is hardware accelerated
or not. Presently we were checking only for hardware acclereated one,
which caused performance to drop to ~0.17Mbps on a 10GbE adapter for
VLAN interface, when tx vlan offload is turned off using ethtool.
The ethernet head length calculation was going wrong in this case, and
driver ended up dropping packets.

Each PF/VF has a limited number of vlan filters for
configuration purposes; This information is passed to qede
and is used to prevent over-usage - once a vlan is to be
configured and no filter credit is available, the driver
would switch into working in vlan-promisc mode.
Problem is the credit pool is shared by both PFs and VFs,
and currently PFs aren't deducting the filters that are
reserved for their VFs from their quota, which may lead
to some vlan filters failing unknowingly due to lack of credit.

The be2net driver performs fw temperature queries on be_worker() routine,
which is executed each second for each be_adapter. There is a frequency
threshold to avoid fw query to happens at each call to be_worker();
instead, currently a fw query occurs once in 64 runs of the procedure.
Nevertheless, this fw temperature query is invoked only for adapters which
interface is up, so we can see I/O errors on read of hwmon counters from
userspace (from tools like lm-sensors) in case we have adapters' functions
which interface is down.
This patch moves the fw query code to be invoked even if interface is down.

Emil fixes the NACK check in ixgbevf_set_uc_addr_vf() for instances where
the index is not equal to zero. Fixes an issue where mac->ops.setup_fc
can be NULL for backplanes which can cause the driver to crash on load.
Don fixes the second parameter of the LED functions, which is the index to

reads to unsigned integer. Adds support for the new x553 hardware into
ixgbevf. Fixed a missing rtnl lock around ixgbevf_reinit_locked().
Fixed an issue where in ixgbevf_reset_subtask() was not verifying that
the port has been removed. Cleans up the initial crosstalk fix, since
the SFP that indicates the presence of a SFP+ module changes between
hardware types.
Babu Moger fixes typo in freeing IRQ, since the array subscript increments
after the execution of the statement.
Wei Yongjun adds the missing destroy_workqueue() before returning from
ixgbe_init_module() in the error handling case.
Tony adds range checking for setting the MTU from the VF, where the PF can
return a NACK but this was not passed on to the VF, so propagate the
results from the PF to the VF so errors can be reported. Consolidates
mailbox read and write functions, since the recent changes to
ixgbevf_write_msg_read_ack(), other functions are performing the same
operations done here.

This series contains updates to i40e and i40evf.
Heinrich Schuchardt found a possible null pointer being dereferenced in
i40e_debug_aq(), fixed the issue by doing the variable assignment after
we are sure the pointer is not null.
Avinash fixed an issue when link was down, we were not showing the
correct advertised link modes.
Mitch cleans up a useless initializer since the variable is assigned
right away. Refactors the receive filter handling to properly track
filter adds and deletes so the driver will not lose filters during a
reset and up/down cycles. Also added a tracking mechanism so that the
driver knows when to enter and leave promiscuous mode.
Catherine removes a device id which is not needed (or used). Moves
a mutex lock since we need to lock the client list around the
i40e_client_release() call to prevent the release from interrupting
the client instances while they are being added.
Joshua adds Hyper-V specific VF device ids.
Amitoj Kaur Chawla cleans up a redundant memset() call before a memcpy().
Stefan Assmann adds the missing link advertise for some x710 NICs.
Tushar Dave fixes and issue found on SPARC, where a PF reset clears MAC
filters and if a platform-specific MAC address is used, the driver has
to explicitly write default MAC address to MAC filters otherwise all
incoming traffic destined to the default MAC address will be dropped
after reset.

Add common library module(libcxgb.ko) for
Chelsio drivers to remove duplicate code.
Code for iSCSI DDP Page Pod Manager is moved
from cxgb4.ko to libcxgb.ko. Earlier only cxgbit.ko
was using this code, now cxgb3i and cxgb4i will
also use common Page Pod manager code.
In future this module will have common connection
management and hardware specific code that can be
shared by multiple Chelsio drivers.
