With the recent changes for how we compute the skb truesize it occurs to me we are probably going to have a lot of calls to skb_end_pointer - skb->head. Instead of running all over the place doing that it would make more sense to just make it a separate inline skb_end_offset(skb) that way we can return the correct value without having gcc having to do all the optimization to cancel out skb->head - skb->head.

Since there is now only one spot that actually uses "fastpath" there isn't much point in carrying it.

The fast-path for pskb_expand_head contains a check where the size plus the unaligned size of skb_shared_info is compared against the size of the data buffer. This code path has two issues. First is the fact that after the recent changes by Eric Dumazet to __alloc_skb and build_skb the shared info is always placed in the optimal spot for a buffer size making this check unnecessary. The second issue is the fact that the check doesn't take into account the aligned size of shared info. As a result the code burns cycles doing a memcpy with nothing actually being shifted.

Clear the REQ and GNT bit in the eeprom control register (EECD). This is required if the eeprom is to be accessed with auto read EERD register. After a cold reset this doesn't matter but if PBIST MAC test was executed before booting, the register was left in a dirty state (the 2 bits where set), which caused the read operation to time out and returning 0.

It appears some networks play bad games with the two bits reserved for ECN. This can trigger false congestion notifications and very slow transferts. Since RFC 3168 (6.1.1) forbids SYN packets to carry CT bits, we can disable TCP ECN negociation if it happens we receive mangled CT bits in the SYN packet.

This change updates the link flow control configuration so that we correctly set the link flow control settings for DCB. Previously we would have to call the fc_enable call 8 times, once for each packet buffer. If we move that logic into the fc_enable call itself we can avoid multiple unnecessary register writes. This change also corrects an issue in which we were only shifting the water marks for 82599 parts by 6 instead of 10. This was resulting in us only using 1/16 of the packet buffer when flow control was enabled.

This change makes it so that ixgbe_fc_autoneg is a void and always sets the current_mode. Previously if the link was down we would return an error, however there is no harm in simply treating a link down case as a case in which autoneg simply failed. This allows us to rely on the return value of the ixgbe_fc_enable call now since there should be no cases where it returns an error that would normally be ignored.

This change reorders the mapping of rings to q_vectors in the case that the number of rings exceeds the number of q_vectors. Previously we would allocate the first R/N queues to the first q_vector where R is the number of rings and N is the number of q_vectors. Instead of doing this we can do a better job of interleaving the rings to the CPUs by assigning every Nth ring to the q_vector. The below tables illustrate this change for the R = 16 N = 4 case. Before patch After patch q_vector: 0 1 2 3 0 1 2 3 Rings: 0 4 8 12 0 1 2 3 1 5 9 13 4 5 6 7 3 6 10 14 8 9 10 11 4 7 11 15 12 13 14 15 This should improve the performance for both DCB or ATR when the number of rings exceeds the number of q_vectors allocated by the adapter.

This change makes it so that we can track instances of where a packet was dropped due to a packet being received when there are no DMA buffers available in the ring. For some reason this was only being enabled with RSC, however it makes more sense to always have this feature on so that we can track any cases where we might drop a buffer due to an Rx ring being full.

The idea here seems to be to get a 44bit DMA mask working and if this fails it should fallback to a 32bit DMA mask. The dma_mask variable is assigned once to 44bit and never updated. pci_set_dma_mask() and pci_set_consistent_dma_mask() are both implemented as functions so there is no evil macro which might update dma_mask. Looking at the assembly, I see a call to dma_set_mask() followed by dma_supported() and then a jump passed the second dma_set_mask(). The only way to get to second dma_set_mask() call is by an error code in the first one. So I hereby remove the check since it looks superfluous. Please ignore the path if there is black magic involved. Signed-off-by: NSebastian Andrzej Siewior <bigeasy@linutronix.de> Signed-off-by: NDavid S. Miller <davem@davemloft.net>
