From 05130d0bc84666ebe2381442c2cbdc0f00e88437 Mon Sep 17 00:00:00 2001 From: Damien Bergamini Date: Wed, 23 Aug 2006 16:25:08 +0000 Subject: the maximum MTU allowed for IEEE802.11 is 2290 which is greater than MCLBYTES (usually 2048). allocate tx xfer buffers of IEEE80211_MTU_MAX instead of MCLBYTES. rx buffers are still limited to MCLBYTES though. --- sys/dev/usb/if_ral.c | 4 ++-- sys/dev/usb/if_rum.c | 4 ++-- 2 files changed, 4 insertions(+), 4 deletions(-) (limited to 'sys/dev') diff --git a/sys/dev/usb/if_ral.c b/sys/dev/usb/if_ral.c index f89e4952a6a..ca6ac137957 100644 --- a/sys/dev/usb/if_ral.c +++ b/sys/dev/usb/if_ral.c @@ -1,4 +1,4 @@ -/* $OpenBSD: if_ral.c,v 1.76 2006/08/23 08:06:49 jsg Exp $ */ +/* $OpenBSD: if_ral.c,v 1.77 2006/08/23 16:25:07 damien Exp $ */ /*- * Copyright (c) 2005, 2006 @@ -450,7 +450,7 @@ ural_alloc_tx_list(struct ural_softc *sc) } data->buf = usbd_alloc_buffer(data->xfer, - RAL_TX_DESC_SIZE + MCLBYTES); + RAL_TX_DESC_SIZE + IEEE80211_MTU_MAX); if (data->buf == NULL) { printf("%s: could not allocate tx buffer\n", USBDEVNAME(sc->sc_dev)); diff --git a/sys/dev/usb/if_rum.c b/sys/dev/usb/if_rum.c index 9c26d0d5fdd..2983e1be1b3 100644 --- a/sys/dev/usb/if_rum.c +++ b/sys/dev/usb/if_rum.c @@ -1,4 +1,4 @@ -/* $OpenBSD: if_rum.c,v 1.36 2006/08/23 16:16:39 damien Exp $ */ +/* $OpenBSD: if_rum.c,v 1.37 2006/08/23 16:25:07 damien Exp $ */ /*- * Copyright (c) 2005, 2006 Damien Bergamini @@ -489,7 +489,7 @@ rum_alloc_tx_list(struct rum_softc *sc) } data->buf = usbd_alloc_buffer(data->xfer, - RT2573_TX_DESC_SIZE + MCLBYTES); + RT2573_TX_DESC_SIZE + IEEE80211_MTU_MAX); if (data->buf == NULL) { printf("%s: could not allocate tx buffer\n", USBDEVNAME(sc->sc_dev)); -- cgit v1.2.3
