done the following changes to improve the RX path KPI
1. remove the extra invalidate in RX path as
we no longer dirty the RX TLV cache lines.
we now store the rx error codes in nbuf cb instead
of RX TLVs reserved memory bytes.
2. with features like flow tag and wds extended mode
enabled by default, the rx_fast_flag is always set
to false, this resulted in lot more instructions
being executed in RX path.
Now we ensured this flag is at least set for other
features which are not enabled by default.

Currently, hardware supports checksum offload for only ipv4, tcpv4/v6 and
udpv4/v6 packets. But driver sets checksum as CHECKSUM_UNNECESSARY for
all rx packets if tcp_udp_err and ip_err bit in rx_attention_tlv is not
set. If driver sets CHECKSUM_UNNECESSARY in skb then network stack will
not validate checksum and will reply to even wrong checksum packets
which is incorrect.
So, fix is to set checksum for all rx packets other than ipv4, tcpv4/v6 and
udpv4/v6 to CHECKSUM_NONE instead of CHECKSUM_UNNECESSARY so that network
stack validates checksum.

Currently the sw_cookie is validated in RX error path
using the pool_id logic, which is not valid for KIWI target.
Kiwi target has a different logic to assign rx sw_cookie, as
compared to other legacy chipsets.
Hence this sanity of sw_cookie fails always for RX error
packets on KIWI target, and these corresponding buffers are
never released/replenished back. Eventually as more RX error
packets are received, the device runs out of buffers in the
refill ring and induces a backpressure.
Hence disable this sanity check for sw_cookie in rx error
path for KIWI target.
