Hi David,
The following pull-request contains BPF updates for your net-next tree.
The main changes are:
1) Detailed documentation of BPF development process from Daniel.
2) Addition of is_fullsock, snd_cwnd and srtt_us fields to bpf_sock_ops
from Lawrence.
3) Minor follow up for bpf_skb_set

Reason:
Discussion started about adding error check on return value where
it was not handled. Also handling the error using IS_ERR_OR_NULL
instead of IS_ERR(), because debugfs_create_dir() doesn't return
error. It returns NULL or a valid pointer when DebugFS is enabled.
Finally it was decided to r

struct stmmac_rx_queue *rx_q = &priv->rx_queue[chan];
priv->rx_queue has size MTL_M
