4688f4f41c net: bcmasp: Keep buffers through power management
There is no advantage of freeing and re-allocating buffers through
suspend and resume. This waste cycles and makes suspend/resume time
longer. We also open ourselves to failed allocations in systems with
heavy memory fragmentation.

1d472eb5b6 net: bcmasp: Add support for ASP 2.2
ASP 2.2 improves power savings during low power modes.

A new register was added to toggle to a slower clock during low
power modes.

EEE was broken for ASP 2.0/2.1. A HW workaround was added for
ASP 2.2 that requires toggling a chicken bit.

d80a523353 ethtool: replace struct ethtool_eee with a new struct ethtool_keee on kernel side
In order to pass EEE link modes beyond bit 32 to userspace we have to
complement the 32 bit bitmaps in struct ethtool_eee with linkmode
bitmaps. Therefore, similar to ethtool_link_settings and
ethtool_link_ksettings, add a struct ethtool_keee. In a first step
it's an identical copy of ethtool_eee. This patch simply does a
s/ethtool_eee/ethtool_keee/g for all users.
No functional change intended.

9b90aca97f net: ethernet: bcmasp: fix possible OOB write in bcmasp_netfilt_get_all_active()
rule_locs is allocated in ethtool_get_rxnfc and the size is determined by
rule_cnt from user space. So rule_cnt needs to be check before using
rule_locs to avoid OOB writing or NULL pointer dereference.

48d17c517a net: bcmasp: Prevent array undereflow in bcmasp_netfilt_get_init()
The "loc" value comes from the user and it can be negative leading to an
an array underflow when we check "priv->net_filters[loc].claimed".  Fix
this by changing the type to u32.
