Previous driver was aligning ring sizes to 16 descs, but hardware actually wants desc ring sizes to be aligned to 32 descs. Signed-off-by:

During dev->open(), make sure we get at least one skb on the Rx ring. Otherwise abort the interface load. Also, if we get skb allocation failures in NAPI poll while trying to replenish the ring, try again later so we don't end up starving out the Rx ring completely. Signed-off-by:

Fix dev->stop shutdown bug where driver was stopping xmit queue and then disabling intrs. Fix is to disable intrs first and then stop the xmit queue, otherwise an interrupt could cause the queue to be rewoken. Also, no need to explicitly do queue servicing because queues are cleaned and reset back to initial state at end of dev->stop. Servicing queues also had the side-effect of also rewakening the xmit queue, which is not what we want. Signed-off-by:

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. Signed-off-by:

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.

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. Signed-off-by:

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. Signed-off-by:

Race condition exists between the cppi_interrupt handler and davinci_interrupt handler w.r.t completing a TX IO. Since DM646x has seperate DMA and USB endpoint interrupts cppi_interrupt handler needs to hold the lock while operating on the endpoint. Update over previous patch to avoid taking the lock if already taken. Tested on DM644x, DM355 and DM646x platforms. Signed-off-by:

This is a (almost) sort-only patch to sort FTDI device product ID definitions in new ftdi_sio_ids.h header. Advantage is that new device ID submissions will now have a specific (sorted) position - less future merge conflicts. Compile-tested, based on _current_ mainline git. Minor checkpatch.pl warnings were eliminated whereever it made sense, very minor text changes. Signed-off-by:
