The e1000e driver is a great user of the usleep_range() API,
and has nice ranges that in principle help power management.
However the ranges that are used only during system startup are
very long (and can add easily 100 msec to the boot time) while
the power savings of such long ranges is irrelevant due to the
one-off, boot only, nature of these functions.
This patch shrinks some of the longest ranges to be shorter
(while still using a power friendly 1 msec range); this saves
100msec+ of boot time on my BDW NUCs

Make use of the struct_size() helper instead of an open-coded version
in order to avoid any potential type mistakes, in particular in the
context in which this code is being used.
So, replace code of the following form:
sizeof(struct virtchnl_ether_addr_list) + (count * sizeof(struct virtchnl_ether_addr))
with:
struct_size(veal, list, count)
and so on...

e1000 writes to doorbells to post transmit descriptors and fill the
receive ring. After writing descriptors to memory but before
writing to doorbells, use dma_wmb() rather than wmb(). wmb() is more
heavyweight than necessary for a device to see descriptor writes.
On x86, this avoids SFENCEs before doorbell writes in both the
Tx and Rx paths. On ARM, this converts DSB ST -> DMB OSHST.

One of the more common cases of allocation size calculations is finding
the size of a structure that has a zero-sized array at the end, along
with memory for some number of elements for that array. For example:
struct foo {
int stuff;
struct boo entry[];
};
size = sizeof(struct foo) + count * sizeof(struct boo);
instance = alloc(size, GFP_KERNEL);
Instead of leaving these open-coded and prone to type mistakes, we can

Changing descriptor count via 'ethtool -G' is not persistent across resets.
When PF reset occurs, we roll back to the default value of vsi->num_desc,
which is used then in i40e_alloc_rings to set descriptor count. XDP does a
PF reset so when user has changed the descriptor count and load XDP
program, the default count will be back there.
To fix this:
* introduce new VSI members - num_tx_desc and num_rx_desc in favour of
num_desc
* set them in i40e_set_ringparam to user's values
* set them to default values in i40e_set_num_rings_in_vsi only when they
don't have previous values

This patch fixes reading f/w LLDP agent status at DCB init time.
It's done by removing direct NVM reading in i40e_update_dcb_config()
and checking whether f/w LLDP agent is disabled via
I40E_FLAG_DISABLE_FW_LLDP flag in i40e_init_pf_dcb(). The function
i40e_update_dcb_config() in i40e_main.c is a temporary solution which
will be later renamed to i40e_init_dcb() in the i40e_dcb module. Also
logging was extended to make visible if f/w LLDP agent is running or not
and always log a message when DCB was not initialized. Without this
patch for new f/w versions f/w LLDP agent status was always read
from NVM as disabled and DCB initialization failed without

Similar to the X540 hardware, enable support for generating a 1pps
output signal on SDP0.
This support is slightly different to the X540 hardware, because of the
register layout changes. First, the system time register is now
represented in 'cycles' and 'billions of cycles'. Second, we need to
also program the TSSDP register, as well as the ESDP register. Third,
the clock output uses only FREQOUT, instead of a full 64bit value for
the output clock period. Finally, we have to use the ST0 bit instead of
the SYNCLK bit in the TSAUXC register.
This support should work even for the hardware with a higher frequency
clock, as it carefully takes into account the multiply and shift of the
cycle counter used.
We also set the pps configuration to 1, since we now support generating
a pulse per second output.
