Add rtnetlink init_rcvwnd to set the TCP initial receive window size
advertised by passive and active TCP connections.
The current Linux TCP implementation limits the advertised TCP initial
receive window to the one prescribed by slow start. For short lived
TCP connections used for transaction type of traffic (i.e. http
requests), bounding the advertised TCP initial receive window results
in increased latency to complete the transaction.
Support for setting initial congestion window is already supported
using rtnetlink init_cwnd, but the feature is useless without the
ability to set a larger TCP initial receive window.
The rtnetlink init_rcvwnd allows increasing the TCP initial receive
window, allowing TCP connection to advertise larger TCP receive window
than the ones bounded by slow start.

Slightly optimize tcp_sendmsg since NETIF_F_SG is used many
times iteratively in the loop. The only other modification is
to change:
} else if (i == MAX_SKB_FRAGS ||
(!i &&
!(sk->sk_route_caps & NETIF_F_SG))) {
to:
} else if (i == MAX_SKB_FRAGS || !sg) {
The reason why this change is correct: this code (other than
the MAX_SKB_FRAGS case) executes only due to the else part
of: "if (skb_tailroom(skb) > 0) {" - i.e. there was no space
in the skb to put the data inline. Hence SG is false is a
sufficient condition, and there is no way a fragment can be
added to the skb.

- Added the above explanation for the change

tcp_push checks tcp_send_head and calls __tcp_push_pending_frames,
which again checks tcp_send_head, and this unnecessary check is
done for every other caller of __tcp_push_pending_frames.
Remove tcp_send_head check in __tcp_push_pending_frames and add
the check to tcp_push_pending_frames. Other functions call
__tcp_push_pending_frames only when tcp_send_head would evaluate
to true.

brightness status is reported by the Apple Cinema Displays as an
'unsigned char' (u8) value, but the code used 'char' instead.
Note that he driver was developed on the PowerPC architecture,
where the two types are synonymous, which is not always the case.
Fixed that. Otherwise the driver will interpret brightness
levels > 127 as negative, and fail to load.

Some of these workarounds are already in place, but labeled as affecting
all BF52x parts. Since we have official anomaly numbers now, use those
defines. And since writing to the FIFO has a similar hang issue as reading
from the FIFO, implement the workaround there too when necessary.

This patch fixes the below array index out of bounds issue.
Buffer overflow, array index of 'aInfo' may be out of
bounds. Array 'aInfo' of size 78 may use index value(s) 6..84
The data stored in 'aInfo' array exceeds the array size of 78.
This patch increases the size of this array to hold the string
correctly without any memory corruption.
This issue was reported by Klockwork tool.
