From 7753b171c4e7604294060d4039214c8c8319bfca Mon Sep 17 00:00:00 2001 From: Jesse Brandeburg Date: Thu, 18 Jan 2007 09:25:31 -0800 Subject: [PATCH] e1000: tune our dynamic itr transmit packet accounting The driver was still mis-calculating the number of bytes sent during transmit, now the driver computes what appears to be exactly 100% correct byte counts (not including CRC) when figuring out how many bytes and frames were sent during the current transmit packet. --- drivers/net/e1000/e1000_main.c | 9 ++++++--- 1 file changed, 6 insertions(+), 3 deletions(-) diff --git a/drivers/net/e1000/e1000_main.c b/drivers/net/e1000/e1000_main.c index 8c6c74d1284a..ae76479d89d1 100644 --- a/drivers/net/e1000/e1000_main.c +++ b/drivers/net/e1000/e1000_main.c @@ -4020,10 +4020,13 @@ e1000_clean_tx_irq(struct e1000_adapter *adapter, if (cleaned) { struct sk_buff *skb = buffer_info->skb; - unsigned int segs = skb_shinfo(skb)->gso_segs; + unsigned int segs, bytecount; + segs = skb_shinfo(skb)->gso_segs ?: 1; + /* multiply data chunks by size of headers */ + bytecount = ((segs - 1) * skb_headlen(skb)) + + skb->len; total_tx_packets += segs; - total_tx_packets++; - total_tx_bytes += skb->len; + total_tx_bytes += bytecount; } e1000_unmap_and_free_tx_resource(adapter, buffer_info); tx_desc->upper.data = 0; -- 2.20.1
