Some chips such as 88E6352 and 88E6390 can be programmed to add delays
to RXCLK for IND inputs or to GTXCLK for OUTD outputs when port is in
RGMII mode.
Add a port function to program such delays according to the provided PHY
interface mode.

Now that we have setters to configure the port's MAC, use them to
refactor the port setup and adjust_link code.
Note that port's MAC speed, duplex or RGMII delay must not be changed

nfp_net_rx() is quite long already and about to get longer.
Move buffer drop/recycle to a helper.

Introduce a separate buffer allocation function to be called
from NAPI. We can make assumptions about the context and
buffer size.

There are few variables in nfp_net_poll() which are used only
once or unused but set. Remove them.

Hi!
This series lays groundwork for upcoming XDP support by updating
the RX path not to pre-allocate sk_buffs. I start with few
cleanups, removal of NFP3200-related code being the most significant.
Patch 7 moves to alloc_frag() and build_skb() APIs. Again, a number
of small cleanups follow. The
Don't declare functions as static inline in .c files and
remove dead code it was hiding.

From: Oliver Hartkopp
Andrey Konovalov reported an issue with proc_register in bcm.c.
As suggested by Cong Wang this patch adds a lock_sock() protection and
a check for unsuccessful proc_create_data() in bcm_connect().

Systems with large pages (64KB pages for example) do not always have
huge quantity of memory.
A big SK_MEM_QUANTUM value leads to fewer interactions with the
global counters (like tcp_memory_allocated) but might trigger
memory pressure much faster, giving suboptimal TCP perfor

Commit 7b7e70f979e3 ("qed*: Allow unicast filtering") introduced several
issues in driver. This series is intended to address and fix those.
Dave,
These are fixes but I believe the original commit hasn't reached net yet.
So please consider applying these to `net-next'.
Thanks,

Driver is now setting the ndev's priv_flags instead of adding to it,
causing pktgen failure to utilize various features due to the loss
of the IFF_TX_SKB_SHARING indication.

When relaxing the limitation on the number of unicast MAC filters
an interface can configure, qed started passing the MAC quota to
qede. However, the value is initialized only for PFs, causing VFs
